The air is then cooled at constant pressure as a result of heat transfer to the surroundings. a. what is the temperature of the air inside the cylinder when the piston reaches the stops? How much work is done during the cooling process? How much heat is rejected? b. The cooling continues after the piston reaches the stops until the temperature reaches 70 °F.. What is the pressure at this state? How much work is done during this process? How much heat is rejected?

Assume 1.62 lb/sec of fluid enter a steady-state, steady-flow system with P1 = 95.18 psia, ρ1 = 0.341 lb/ft3, v1 = 93.75 fps, u1 = 798.07 BTU/lb, and leave with P2 = 16.73 psia, ρ2 = 0.134 lb/ft3, v2 = 427.15 fps, and u2 = 761.09 BTU/lb. During the passage through the open system, each pound rejects 11 BTU of heat. Determine the work in hp.
