Hi, Basically I'm doing a experiment, and part of is looking at the draining time of water over a certain distances. I've got the data but unsure how to put it into a graph. The data goes something like this: Water heights [mm] Velocity of water [m/s] 120 - 90...

thanks for the help! much appreciated.

Ahhh yes. Must have missed these figures! 14.7psi = 1 atmosphere = 101,325 Pa And its 6.894 757 kPa to 1 psi. So if i were to write a sentance would something like this be correct? "The pressure at combustion is 200psi. To show how high this pressure is, i converted it to Pascals, which is...

Pascals - Atmospheres I have a various numbers of psi's...and was told it would be interesting to convert it to pascals, and then compare the pascals and our atmosphere. As in, 200 psi is 1.38e10^6 Pa. How could i show how much force that is. Or even say, its 'x' number of atmospheres. Just so...

Hi, I need some help concerning the Carnot cycle [i've searched, but what i needed didn't come up]. I am trying to work out the efficiency of a 4 or 2 stroke motorcyle engine. [car engine, it doesn't matter really]. But I'm having some difficulty finding temperatures for the hot and cold...
