An ideal Rankine cycle with reheat uses water as the working fluid. As shown below, the conditions at theinlet to the first turbine stage are 1600 lbf/in2, 1200◦F and the steam is reheated to temperature T3 between the turbine stages at a pressure of 200 lbf/in2 For a condenser pressure of 1 lbf/in2, plot the cycle thermal efficiency versus reheat temperature and plot the cycle thermal efficiency versus quality of the steam at the second-stage turbine exit for there heat temperature ranging from 600◦F to 1200◦F.
