P5) A steam power plant operates under the ideal Rankine cycle. Here, the steam at the inlet of the turbine is at 3 MPa and 350 C and the exit

of the condenser at 10 KPa. Find: a) The thermalefficiency of the power plant b) The thermalefficiency if steam is superheated to 600C instead of 3500 c) The thermal efficiency if the boiler pressure is elevated to 15MPA whilst the intet temperature ofthe turbine is kept at 600C.
