1. A steam power plant operating on Carnot cycle receives heat from a furnace at a rate of 320 GJ/h. Heat losses to the surrounding air from the steam as it passes through the pipes and other components are estimated to be about 10 GJ/h. If the waste heat is transferred to the cooling water at a rate of 165 GJ/h, determine (a) net power output, in MW and (b) the thermal efficiency of this power plant in percent.
