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 = 400 lbf/in.² Part A Reheat section Steam generator X4= |P6=P₁=1600 lbf/in.² 6+ Ps= P₂ 3 T3 P1 = 1600 lbf/in.² T₁ = 1200°F For a condenser pressure of ps=p4 = 9 lbf/in.², determine: (a) the quality of the steam at the second-stage turbine exit. (b) the cycle percent thermal efficiency. Pump P₂ Turbine 1 Ps= P4 x=0 (saturated liquid) Turbine 2 PA Condenser h6≈ h5 + V5 (P6 - ps)Determine the quality of the steam at the second-stage turbine exit. 4
