A Carnot vapor power cycle operates with water as the working fluid. Saturated liquid enters the boiler at 1400 lbf/in., 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 105 lb/h. Data at key points in the cycle are provided in the accompanying table. Determine: State p (lbf/in.2) h (Btu/lb) 1 2 3 4 1400 1.2 1.2 1400 1174 758.3 446.5 598.8 (a) the percent thermal efficiency. (b) the back work ratio. (c) the net power developed, in Btu/h. (d) the rate of heat transfer to the working fluid passing through the boiler, in Btu/h.
