I don't think I said P = const, I just didn't know how to analyze the work now after finding the final pressure but the link helped, I remember the process now. I said that because its isothermal, you can say Q = W because all heat transfer is in the form of work since there is no change in...

So, would you use Pv=RT, where you have temperature, where you know P, V, R, T so you can just use that to find m where m = V/v. V=volume, v = specific volume? Now, you know the new V, you have T, you have mass, you have R, so you can solve for P? P = RT/v = RT/(V/m) Then the work required to...

Okay yea I missed the dimensions, so the volume is the volume of a cylinder using diameter and height, thanks! With the 340 liters of water and the mass, I can find specific volume and then since its isothermal I have 20 celsius. I can then use those two to look up the pressure in the steam...

1. The problem statement, all variables and given/know In rural communities where landowners have their own water wells, large tanks are used to store water, which is pressurized by a sealed “air cushion”. Water is pumped intermittently from the well to restore the tank supply when the level is...
