However, most measurements are still made in centistokes, e.g. Viscosity - Converting Chart Convert between viscosity units like Centiposes, milliPascal, CentiStokes and SSU. Kinematic Vicosity is a fluid's resistance to flow and can be valued as dynamic (absolute) or kinematic. Thus water at 20 ✬ has a kinematic viscosity 1,002 The experiments were conducted at free stream velocity ranging from 2 m/s to 4 m/s. Dynamic viscosities of sucrose water solutions vs. Usually, increased temperature reduces the viscosity of a liquid and makes it more hazardous. On the previous IPTS-68 scale, the densities at 20 C and 4 C are 0.9982041 and 0.9999720 respectively, resulting in an SG (20 C/4 C) value for water of. Kinematic viscosity () designates the quotient of the dynamic viscosity of the fluid handled and its density. Liquids with lower viscosity are generally more hazardous because they can spread more quickly. Water at 20 ☌ has a kinematic viscosity of about 1 cSt. 7 If a certain gasoline weighs 43 lb/ft3, what are the values of its density, specific volume, and specific gravity relative to water at 60F Use Appendix A. Other units used include St and cSt.ġ cSt (centiStoke) = 1 mm2/s = 10^(?6)m2/s The SI unit of the kinematic viscosity is m2/s. The kinematic viscosity is the ratio between the dynamic viscosity and the density of a fluid. If the surface tension of water is 0.07275 Nm-1 and density 0.9982 x 103 kg m-3, calculate the ratio of number of drops of liquid to that of water Solution. Kinematic Viscosity is a measure of the resistive flow of a fluid under the influence of gravity. A 15 kg block slides down a 25-degree inclined plane on a 0.2-mm-thick film of SAE 30 oil gap at a temperature of 60-F. The kinematic viscosity of 1 ft/s is equivalent to how many stokes 3. You can often find it in the section 9 of a safety data sheet (SDS).ĭynamic Viscosity is a measure of a liquid’s resistance to its shearing flows, where adjacent layers move parallel to each other with different speeds. If the dynamic viscosity of water at 20-C is 1 E-3 N-s/m, what is the kinematic viscosity in the English units 2. There are two types of viscosity: Dynamic viscosity and Kinematic viscosity.

Use a client/player that is fully compatible with what you are playing, including codecs.įor example: Plex client in Chrome obviously cannot stream mkv files, so processing on the server side is required.Īt the same time, a standalone Plex app can direct play those mkvs, given that the machine the app running on have enough power to do so.ĭownload the file and then open it locally via something that can properly play it, not a browser.

So don’t blame Google for not streaming you original quality, as you probably should thank them for providing an option to stream or show you most files on whatever device that you have, including a browser on a PC, or a phone, or a freezer. It actually does makes sense as a browser does not have a codec to play mkv, for example, so a file have to be processed first and then streamed back to you in dash-like segments.

1/8/2024 0 Comments Anti lock braking system pump![]() ![]() ABS won’t help with that – but that’s where Electronic Stability Control comes in. ![]() There’s also the potential for tyres to slip sideways if cornering too fast. That rapid bursting is what makes the characteristic ABS crunching noise.ĪBS just controls the ‘straight line’ action of the tyres on the road, but that was sufficient for my purposes yesterday. It’s like what you need to do on a non-ABS car (probably there aren’t too many of these on the roads any more) – pump the brake pedal yourself. It allows the braking to take full effect, but then releases the brakes momentarily when they ‘lock’, before applying the braking again. The ABS senses when the wheels have locked, and then pumps brake fluid in bursts. You will take longer to stop with sliding tyres than with rolling tyres. But also, since the coefficient of kinetic (or ‘sliding’) friction is generally less than the coefficient of static friction ( EngineeringToolbox gives about 0.5-0.8 for rubber against dry asphalt), it means that the total braking force is lower. ![]() First it means that you have lost control of the car, and it doesn’t do your tyres any good. If the braking on a moving car is too severe, the frictional force between the road and the tyre is insufficient to keep the tyre sticking to the road, and thus ‘rolling’. However, there is a limit to that frictional force, and this is why wheels can lock and cars slide, especially on a wet, icy or loose-surface road. The frictional force between the road and the tyres is sufficient to prevent the car from sliding backwards down the hill. It also means that, by applying the handbrake and locking the wheels, the car can park happily on some very steep gradients, provided it’s not icy. The bit of the tyre in contact with the ground is always stationary with respect to the ground. Rubber against dry asphalt has a high coefficient of static friction (a measure of stickiness between surfaces) – EngineeringToolbox gives it as about 0.9 – which means that when a car is moving forward the tyres are rolling, not sliding, along the road. Braking ultimately depends on how good your tyre’s grip with the road is. ![]() 1/8/2024 0 Comments CrossOver free instal![]() ![]() By downloading the Citrix Workspace app, you can get instant access to applications, data, and desktops.Īside from your Chromebook, you can access this server using a Macbook, tablets, and smartphones.

1/7/2024 0 Comments Tidal energy examples![]() ![]() A tidal range of at least 7 m is required for economical operation and for sufficient head of water for the turbines. Tidal range may vary over a wide range (4.5-12.4 m) from site to site. Barrages can be designed to generate electricity on the ebb side, or flood side, or both. The dam includes a sluice that is opened to allow the tide to flow into the basin the sluice is then closed, and as the sea level drops, the head of water (elevated water in the basin) using traditional hydropower technology, drives turbines to generate electricity. Traditional tidal electricity generation involves the construction of a barrage across an estuary to block the incoming and outgoing tide. Where are good areas for exploiting tidal energy? The 25-30 ft tidal variations of Passamaquoddy Bay (Bay of Fundy) have the potential of between 800 to 14,000 MWe. The total world potential for ocean tidal power has been estimated at 64,000 MWe. A drawback of tidal power is its low capacity factor, and it misses peak demand times because of 12.5 hr cycle of the tides. Most modern tidal concepts employ a dam approach with hydraulic turbines. Tidal streams can be harnessed using offshore underwater devices similar to wind turbines. By building semi-permeable barrages across estuaries with a high tidal range.īarrages allow tidal waters to fill an estuary via sluices and to empty through turbines.Tidal energy can be exploited in two ways: Unlike wind and waves, tidal currents are entirely predictable. Tidal power is non-polluting, reliable and predictable.Tidal barrages, undersea tidal turbines – like wind turbines but driven by the sea – and a variety of machines harnessing undersea currents are under development. We even have one remaining in New York- which worked well into the 20th century. The tides turned waterwheels, producing mechanical power to mill grain. ![]() Tide mills consisted of a storage pond, filled by the incoming (flood) tide through a sluice and emptied during the outgoing (ebb) tide through a water wheel. Indeed, tide mills, in use on the Spanish, French and British coasts, date back to 787 A.D. Tidal energy is one of the oldest forms of energy used by humans. ![]() ![]() These indicators appear as their own graph below the main stock graph.

In crystal structures of RNAP σ holoenzyme, the RNAP active-centre cleft is too narrow to accommodate double-stranded DNA (dsDNA) (<20 Å), and σ obstructs access of dsDNA to the RNAP active-centre cleft ( Mekler et al., 2002 Murakami et al., 2002b Murakami et al., 2002a Vassylyev et al., 2002). However, the mechanism by which DNA is unwound and loaded into the RNAP active-centre cleft has remained controversial (reviewed in Mazumder and Kapanidis, 2019). Structural and biochemical experiments suggest that transcription-bubble formation is initiated by unwinding the DNA base pair at the upstream end of the transcription bubble – breaking the base pair, and unstacking and flipping the non-template-strand base of the broken base pair, and inserting the unstacked and flipped non-template-strand base into a protein pocket of σ – followed by propagation of the unwinding in a downstream direction ( Mazumder and Kapanidis, 2019 Ruff et al., 2015 Zhang et al., 2012 Feklistov and Darst, 2011). High-resolution structures of RPo define the contacts that RNAP and σ make with promoter DNA, as well as the conformation and interactions of unwound template-strand ssDNA engaging the RNAP active centre ( Bae et al., 2015 Zuo and Steitz, 2015 Zhang et al., 2012). During transcription initiation, RNA polymerase (RNAP), together with the transcription initiation factor σ, unwinds ~13 bp of promoter DNA to form a ‘transcription bubble’, and places the template-strand ssDNA of the unwound transcription bubble in contact with the RNAP active centre, yielding a catalytically competent RNAP-promoter transcription-initiation complex (RPo Mazumder and Kapanidis, 2019). Transcription initiation is the first and most highly regulated step in gene expression ( Mazumder and Kapanidis, 2019 Ruff et al., 2015). Our work defines a new, ‘bind-unwind-load-and-lock’, model for the series of conformational changes occurring during promoter unwinding at a consensus bacterial promoter and provides the tools needed to examine the process in other organisms and at other promoters. We find that the RNAP clamp is closed during promoter binding, remains closed during promoter unwinding, and then closes further, locking the unwound DNA in the RNAP active-centre cleft. Here, using single-molecule unwinding-induced fluorescence enhancement to monitor promoter unwinding, and single-molecule fluorescence resonance energy transfer to monitor RNAP clamp conformation, we analyse RPo formation at a consensus bacterial core promoter. Despite extensive study, the mechanism of promoter unwinding has remained unclear, in part due to the transient nature of intermediates on path to RPo. ![]() ![]() Transcription initiation starts with unwinding of promoter DNA by RNA polymerase (RNAP) to form a catalytically competent RNAP-promoter complex (RPo). ![]() ![]() ![]() Mickey, Sora, Donald, and Goofy at the Great Maw.Īlthough a small minority of Heartless attack Ansem the Wise's old castle, Sora and his friends force them back out of the town into the Great Maw. They appear to be mostly unscathed, and quickly begin working on repairing the town once more. They do not appear again until after the fight, but it can be assumed that they spent most of the time fighting close to the town, defending it from advancing Heartless. Even Stitch, Yuna, Rikku, and Paine help in defeating the Heartless, although they do not have as much of an effect on their numbers.Īs Sora and the gang make their way down the Ravine Trail toward the Great Maw, the Committee arrives in various places to help them reach their destination, then disappears to continue the fight. Later, Cloud has a short reunion with Sephiroth, then runs off after him just as Tifa arrives. Cloud and Leon fight side-by-side against a large crowd of Heartless, both making comments regarding their capabilities in defeating them. Aerith aids Yuffie with her white magic skills, casting the Cure spell. They ready themselves as thousands upon thousands of Heartless flow toward the town. Meanwhile, the Hollow Bastion Restoration Committee makes their way towards the Bailey, and then to the Great Maw, to combat the threat. When the Bailey is destroyed by the surge of Heartless, the party immediately makes their way there, but they must fight their way out of the halls of the castle to get there. The battle begins after Sora and company open the DTD dataspace in Ansem's computer and discuss Ansem's identity with the King. In one interview, Nomura stated that he had almost considered dropping the battle from Kingdom Hearts II entirely, due to the incredible amount of effort needed to program the battle into the game. This cutscene is replaced in Kingdom Hearts HD 2.5 ReMIX with the final scene from Kingdom Hearts II. The Behemoths and Wyverns were excluded from the final game, although this version of the cutscene appears in the opening of Kingdom Hearts Re:coded. The promotional trailers for Kingdom Hearts II depicted Sora, Donald, and Goofy running towards the horde of Heartless, which included a new kind of Behemoth and several Final Mix-design Wyvern. This is because the cutscene was pre-rendered, probably because of the high amount of objects in the area. However, when the fight starts, they carry their equipped weapons.

It’s a clear indication that the battery is not able to supply enough power to start the engine. The engine may take longer than usual to start, or you may need to turn the ignition key multiple times. One of the first signs of a battery drain issue in a Ford Escape is difficulty in starting the vehicle. Symptoms Signifying Battery Drain Issues in Ford Escape Vehicle Startup Difficulties This article aims to provide a practical guide on the causes, symptoms, and solutions to this problem. The crux of this problem lies in the unexpected loss of battery charge, even when the vehicle is not in use. This recurring issue affects the overall performance of the vehicle, specifically in terms of electrical systems and startup. The Ford Escape, a popular compact SUV, has seen instances of a peculiar problem – battery drain. Background on the Ford Escape Battery Drain Problem Regular maintenance and timely repairs are the best ways to prevent such problems. In summary, the Ford Escape battery drain problem is a multi-faceted issue, originating from several potential causes that car owners should be aware of. Poor grounding, too, can lead to irregularities in the electric flow, thus draining the battery. A software update may fix battery draining problems caused by this reason. Outdated software can also lead to issues with power management. This could also be due to a malfunctioning battery, unable to hold a charge, or worn-out cables that impede proper power transfer. Similarly, faulty relays and defective fuses can disrupt the electrical circuit, leading to battery depletion.įurthermore, ignition switch problems can result in power being supplied to the car’s electrical components even when the ignition is off. The alternator should charge the battery when the vehicle is running, but if it’s not working properly, it can drain the battery instead. Alternator issues also play a critical role in this problem. ![]() 1/6/2024 0 Comments No pocket billiards rules![]() ![]() Scores are also cumulative, so if a player accomplishes more than one possibility in a shot, they are added. During this shot, the cue ball cannot contact another object ball or it is a foul. A player must score their 101st point by caroming the cue ball off the one ball into a called pocket. And if that weren’t enough, there is a specialized way to get the last point. This means that for either 10 shots or 5 shots, you need to make the cue ball kiss off of two-three balls each time to make ten of the last eleven points. Another little hitch is that for points 91-100, they can only be scored by making successful carom shots. Remember that no points are added for a fouled shot. When a player makes their 90th point, it must come out to exactly 90, or the shot is considered a foul. Sounds simple right? Well, here is where the tricks begin. If there is a scratch or jumped cue ball, the incoming player has ball in hand behind the headstring, the object balls remain in position unless one or more was pocketed. Unless the cue ball is scratched or jumped, the incoming player simply accepts the table as it lies. There are no point penalties for fouls, and after each shot any pocketed balls are spotted in their original positions. Also, a carom off two object balls is equal to one point, and a carom off all three object balls is worth two points. Example, the one ball is worth one point when pocketed. The scoring system in Cowboy is that each ball carries a point value equal to it’s number. The balls do not have to be pocketed in any specific order, except the break off ball and the last ball.Īfter the three ball is contacted on the break, any ball may be targeted for a shot. After contact on any shot, the cue ball or an object ball must be driven to a cushion, or the shot results in a foul. The breaking player must contact the three ball first. The first player has cue ball in hand behind the head string. The one ball is placed on the headspot, the three ball on the footspot, and the five ball on the center spot in a straight line. There is no “rack”, and it is only played with the 1, 3, and 5 balls. This is the North American game of Cowboy, and is a great way to practice specific aiming systems and improve your critical thinking in pool.Ĭowboy starts a little differently than other pocket billiards games. It can be very challenging, but incredibly fast paced. ![]() The game virtually has no tournament history, however, and is primarily played by amateurs who wish to combine the carom sports with pocket billiards. Believe or not, today’s modern name game is an offshoot of a game developed in England in 1885, which was known as Thirty-Eight. ![]() |
