Question:
A vapor-compression cycle is specified by a closed, counterclockwise loop in the ST-plane. Show that if the loop is executed reversibly then the area of the loop is equal to the net work performed on the fluid in a cycle. Explain why the area of the ideal VC cycle {1234} in Figure 13.5(b)
is not equal to the work performed on the fluid.
