Considering Reheat and Supercritical Cycles

An ideal Rankine cycle with reheat uses water as the working fluid. The conditions at the inlet to the first-stage turbine are p1 = 2500 lbf/in.2, T1 = 1000oF. The steam is reheated at constant pressure p between the turbine stages to 1000oF. The condenser pressure is 1 lbf/in.2

(a) If p/p1 = 0.2, determine the cycle thermal efficiency and the steam quality at the exit of the second-stage turbine. (b) Plot the quantities of part (a) versus the pressure ratio p/p1 ranging from 0.05 to 1.0.
