A simple Rankine cycle is implemented in a steam power plant. The working fluid used is water. Water enters the pump at 25 kPa whereas the superheated steam enters the turbine at SMPa. The highest temperature in the Rankine cycle is recorded at 600 °C. Taking the isentropic efficiency of the pump to be at 80% and the isentropic efficiency of the turbine to be 88%, determine the following information if the pump is constantly delivering water at a rate of 5 kg/s. 1) The quality of vapor exiting the turbine ii) 111) Actual power required to operate the pump Actual power generated by the turbine

A simple Rankine cycle is implemented in a steam power plant. The working fluid used is
water. Water enters the pump at 25 kPa whereas the superheated steam enters the turbine at
8MPa. The highest temperature in the Rankine cycle is recorded at 600 °C. Taking the
isentropic efficiency of the pump to be at 80% and the isentropic efficiency of the turbine to be
88%, determine the following information if the pump is constantly delivering water at a rate
of 5 kg/s.
