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
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?
