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.2, 1200°F and the steam is reheated to a temperature of T3 = 800°F between the turbine stages at a pressure of p3 = p2 = 200 lbf/in.2 For a condenser pressure of p5 = p4 = 1 lbf/in.2, determine: (a) the quality of the steam at the second-stage turbine exit. (b) the cycle percent thermal efficiency.
