1.5An 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. h6≈h5+v5(p6−p5)h6≈h5+v5(p6-p5)Determine the quality of the steam at the second-stage turbine exit. x4 = (b) the cycle percent thermal efficiency.

1.5An 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.
x4 =
(b) the cycle percent thermal efficiency.
(a) the quality of the steam at the second-stage turbine exit.
h6≈h5+v5(p6−p5)h6≈h5+v5(p6-p5)Determine the quality of the steam at the second-stage turbine exit.
x4 =
(b) the cycle percent thermal efficiency.
