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.

Solutions

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%.
