Considering Reheat and Supercritical CyclesSteam at 4800
Chapter 8, Problem 34P(choose chapter or problem)
Steam at \(4800 \mathrm{lbf} / \mathrm{in}^2, 1000^{\circ} \mathrm{F}\) enters the first stage of a supercritical reheat cycle including two turbine stages. The steam exiting the first-stage turbine at \(600 \mathrm{lbf} / \mathrm{in.}^2\) is reheated at constant pressure to \(1000^{\circ} \mathrm{F}$. Each turbine stage and the pump has an isentropic efficiency of 85%. The condenser pressure is \(1 \mathrm{lbf} / \mathrm{in}^2\) If the net power output of the cycle is \(100 \mathrm{MW}\), determine
(a) the rate of heat transfer to the working fluid passing through the steam generator, in MW.
(b) the rate of heat transfer from the working fluid passing through the condenser, in MW.
(c) the cycle thermal efficiency.
