The pressure in the boiler of a steam power plant operating on the ideal Rankine cycle is 1250 psia. The condenser pressure is 2 psia. The mass flow rate of steam through the system is 75 lbm/s and the quality of the steam at the turbine exit is 0.9. The pump adds 3.75 Btu/lbm of work to the fluid. Show the cycle on a T-s diagram, and determine (a) the turbine inlet temperature, (b) the rate of heat input in the boiler, and (c) the thermal efficiency of the cycle.
