A piston-cylinder apparatus contains argon at initial conditions of 15 psia, 70F, and 0.30 ft³. The argon is then compressed slowly and frictionlessly to a final pressure of 150 psia. Heat transfer between the argon and the surroundings at 60F causes the temperature to remain constant throughout the compression process. Determine (a) the argon mass (lbm), (b) the final volume (ft³), (c) the work for the process (ft-lbf), (d) the heat transfer (BTU), and (f) the total entropy generation for the process (BTU/R). (f) Why is this process irreversible?

Expert Solution

Hello there. I have converted units into SI units (wherever needed) because it is easier to deal with SI units. But I have given the final answers in the required units only. Also I have mentioned unit conversion scale in the beginning. Please find the attached solution.

A cylinder fitted with a piston has an initial volume of 0.1 m3 and contains nitrogen at 150 kPa, 25 0C. The piston is moved, compressing the nitrogen until the pressure is 1 MPa and the temperature is 150 0C. During this compression process heat is transferred from the nitrogen, and the work done on the nitrogen is 20 kJ. Determine the amount of this heat transfer.
