Mechanical Engineering

Steam at 4800 lbf/ in.2, 1000°F enters the firststage of a supercritical reheat cycle including two turbine stages.The steam exiting the first-stage turbine at 600 lbf/in.2 is reheated at constant pressure to 1000°F. Eachturbine stage and the pump has an isentropic efficiency of 91%. Thecondenser pressure is 1 lbf/ in.2 If the net poweroutput of the cycle is 100 MW, determine

(a) the rate of heat transfer to the working fluidpassing through the steam generator, in MW.
(b) the rate of heat transfer from the workingfluid passing through the condenser, in MW.
(c) the cycle thermal efficiency.
