Three lb of water is contained in a piston–cylinder assembly, initially occupying a volume V1 5 30 ft3 at T1 5 300°F. The water undergoes two processes in series:

Process 1–2: Constant-temperature compression to V2 5 11.19 ft3, during which there is an energy transfer by heat from the water of 1275 Btu.

Process 2–3: Constant-volume heating to p3 5 120 lbf/in.2

Sketch the two processes in series on a T–y diagram. Neglecting kinetic and potential energy effects, determine the work in Process 1–2 and the heat transfer in Process 2–3, each in Btu.
