My humblest apologies. I made a terrible mistake. The above equation dV = 1.003 dT is incorrect. The incompatibility of the units should have told me this equation was wrong. The proper equation is: dV/Vo = 0.003 (1/degree K) dT (where V = volume, Vo = initial volume of the tank...

Thanks, Dullard and gmax137. From what you said, and from what else I gather, as the temperature increases, the vapour pressure will increase, but remain initially irrelevant to the problem. When the temp hits + 26 C, the tank will be 100% liquid. Presumably the pressure in the tank at this temp...

The Propane industry mandates that a tank not be filled more than 80%. The question I have is this: how do I calculate the limit of liquid propane in a standard 3800 liter tank given a 30 degree rise in temperature (from 273 K to 303 K) such that it will not rupture the tank? For example, can I...

Whenever dealing with equations, it is necessary to let the textbook define the variables - as not all textbooks use the same definitions. All that said, in aerodynamics, it is normal to define the drag coefficient as the sum of the profile drag and the induced drag. CD = Cd + k CL2 The left...

Wow. Thank-you so kindly SteamKing!

I've been doing some study and repeatedly end up again at Bradley's experiments that discovered the way gamma draconis fluctuated in angle to the tune of 20 arc-seconds per year. I've been trying to track down a bunch of questions on this, but have not succeeded, so I thought I would see if I...
