Water is the working fluid in an ideal Rankine cycle. Steam enters the turbine at 1400 lb/in² and 1000°F. The condenser pressure is 2 lb/in.2 The net power output of the cycle is 200 MW. Cooling water experiences a temperature increase from 60°F to 76°F, with negligible pressure drop, as it passes through the condenser. Step 1 Determine the mass flow rate of steam, in lb/h.

2. An internally reversible heat engine operates between intake and heat release temperatures between 627 and 27 °C. Part of the work generated by the heat engine is used to move an internally reversible refrigeration machine that works between temperatures of 27 and -23 °C. The heat supplied to the engine is 2100 kJ and the net work output (the work of the engine minus that consumed by the refrigerating machine) is 500 kJ.
