Question
An ideal Rankine cycle with reheat uses water as the working fluid. As shown in the figure below, the conditions at the inlet to the first
turbine stage are 1600 lbf/in.?, 1200°F and the steam is reheated to a temperature of T3 = 800°F between the turbine stages at a
pressure of p3 = P2 = 400 lbf/in.2
