An ideal reheat rankine cycle with water as the working fluid operates the inlet of the high-pressure turbine at 8000 kpa and 450°c, the inlet of the low-pressure turbine at 500 kpa and 500°c, and the condenser at 10 kpa. determine the mass flow rate through the boiler needed for this system to produce a net 5000 kw of power and the thermal efficiency of the cycle.
