A steam engine converts 1500 million Btu input energy obtained by burning a fuel into mechanical energy. Steam goes into the turbine at 250 ∘C and condensed water leaves the turbine at 30 ∘C. Assuming that the turbine operates as an ideal Carnot engine determine the mechanical energy output in MWh.
