5. A piston-cylinder device that contains water substance is used to execute a Carnot heat-engine cycle. From an initial state of saturated liquid at 500∘F (state 1), the fluid is expanded isothermally until the pressure is 600psia(Ib/in2) (state 2). The process is followed by an isentropic expansion to 200∘F (state 3). For the the cycle, determine 1) The thermal efficiency, and then 2) The heat supplied, 3) The heat rejected, and 4) The work during isentropic expansion, all in Btu/lbm. 5) Sketch these processes in a T-s diagram.
