A steam power plant implements an ideal reheat Rankine cycle. Steam enters the inlet of thigh-pressure turbine at 8 MPa and 450 Celsius and the inlet of the low-pressure turbine at 0.5 MPa and 500 Celsius. The condenser operates at 10 kPa. Determine:
(a) The mass flow rate through the boiler needed for the system to produce a net 6000 kW of power
(b) The thermal efficiency of the cycle
