Problem- A power plant using an ideal Rankine power generation cycle operates at an evaporator pressure of 10 MPa with an outlet temperature of 900°C in the evaporator. The condenser operates at a pressure of 100 kPa and produces saturated liquid water. Determine the following:
1) The work produced by the turbine.
2) The heat given off by the condenser.
3) The work required by the pump.
4) The heat used by the boiler.
5) The overall efficiency of this Rankine cycle.
