A Carnot vapor power cycle operates with water as the working fluid. Saturated liquid enters the boiler at 1400 lbf/in.2, and saturated vapor enters the turbine (state 1). The condenser pressure is 1.2 lbf/in.2 The mass flow rate of steam is 5.5 x 106 lb/h. Data at key points in the cycle are provided in the accompanying table. State 1 2 3 4 p (lbf/in.²) 1400 1.2 1.2 1400 h (Btu/lb) 1174 758.3 446.5 598.8
