A simple Rankine-cycle steam power plant operates with a steam flow rate of 500,000 lb_m/hr. Steam enters the turbine at 500 psia and 1000 F. The turbine exhaust (condenser inlet) conditions are 1.0 psia with a steam quality of 0.90. Determine the following: 

A. The turbine output (kW)

B. The condenser heat rejection rate (Bt_u/hr)

C. The turbine isentropic efficiency (%)

D. Each term in the second-law entropy balance for the condensing process

E. The approximate pump work (kW)

F. The thermal efficiency of the plant (%)

G. The ideal thermal efficiency of the plant (%)
