A steam power plant operates on the reheat rankine cycle between 15 mpa and 10 kpa. System enters the high pressure turbine at 15 Mpa and 500c at rate of 12 kg/s. steam is then reheated at constant pressure to 500c befe it expands in the low pressure turbine. The isentropic efficiencies of the turbine and the pump are 85% and 90% respectively. Steam leaves the condenser as saturated liquid.

Determine

1- Net power out put

2- Thermal efficiency
