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 ofT
3 = 800°F between the turbine stages at a pressure ofp
3 =p
2 = 400 lbf/in.2



For a condenser pressure ofp
5 =p
4 = 9 lbf/in.2, determine:
(a) the quality of the steam at the second-stage turbine exit.
(b) the cycle percent thermal efficiency.
