In a steam power plant, dry saturated steam enters the turbine at a pressure of 40 bar and exits the turbine at a pressure of 0.1 bar. The turbine has an isentropic efficiency of 90 %, and the condensate pump has an isentropic efficiency of 85 %. The water/steam mass flow rate through the plant is 200 kg/s, and all changes in kinetic and potential energy are negligible. Using this information, determine:

Question
In a steam power plant, dry saturated steam enters the turbine at a pressure of 40 bar and
exits the turbine at a pressure of 0.1 bar. The turbine has an isentropic efficiency of 90 %, and
the condensate pump has an isentropic efficiency of 85 %. The water/steam mass flow rate
through the plant is 200 kg/s, and all changes in kinetic and potential energy are negligible.
Using this information, determine:
a) The power output of the turbine, in MW.
b) The power required by the pump, in MW.
