A piston-cylinder device has an initial contained volume of, Ask an Expert

Engineering

A piston-cylinder device has an initial contained volume of 0.1 ft³ and contains steam at an initial state of 160 psia, 500°F. The steam is then expanded to 20 psia, 0.65 ft³ and as a result of this process 0.50 Btu of heat is transferred to the system. Assume that the atmospheric conditions are 14.7 psia and 80°F.

a. Find the actual useful work done by the system.

b. Find the change in availability during the process.

c. What is the second law efficiency of the process?
