In a reheat-cycle power plant, steam enters the high-pressure turbine at 5MPa and 450°C then expends to 0.5MPA, after which is reheated to 450 C. The steam is then expended through the low-pressure turbine to 7.5kPa. If the total power output of the two turbines is 10MW, determine the mass flow rate of the steam and the thermal efficiency (ignore the pump work). (Sketch the cycle on P-V and T-S diagrams)
