An ideal Rankine cycle operates with a turbine inlet pressure of 900 psia and a turbine inlet temperature of 572 oF. The steam is isentropically expanded through the turbine to 5 psia as illustrated on the T-s diagram shown below. Using the Mollier diagram, determine the percent moisture at the turbine outlet under these operating conditions. State your answer in whole numbers.

Expert Solution

1. Draw point 1 at T₁ = 572^oF and P₁ = 900 psia. It shows the inlet condition of turbine.

2. Draw vertical line intersecting pressure line P₂ = 5 psia. This point shows outlet condition of turbine. corrensponding value of dryness fraction x₂ = 0.77, It means that moisture is 77%.
