Water is the working fluid in a vapor power cycle with reheat, superheat and reheat.

Superheated steam enters the first turbine stage at 8 MPa, 480 C and expands to 0.7 MPa. It then is reheated to 480 C before entering the second turbine stage, where it expands to the condenser pressure of 8 KPa. The mass flow rate of steam entering the first turbine stage is 2.63*10^5 Kg/h. Each turbine stage operates with an isentropic efficiency of 58%. The pump operates with an efficiency of 80%.

Determine the net power developed, the cycle thermal efficiency and the rate of heat transfer to the cooling water passing through the condenser.
