A turbine is supplied with steam at a pressure of 30 bar and a temperature of 400C. The steam then expands isentropically to a pressure of 0.08 bar. Find the dryness fraction at the end of expansion and thermal efficiency of the cycle. If the steam is reheated at 5 bar to a temperature of 400C and then expanded isentropically to a pressure of 0.08 bar, what will be the dryness fraction and thermal efficiency of the cycle? Draw the T-s diagram and explain. A turbine is supplied with steam at a pressure of 30 bar and a temperature of 400C. The steam then expands isentropically to a pressure of 0.08 bar.
