Figure P4.104 provides steady-state operating data for a cogeneration system with water vapor at 20 bar, 3608C entering at location 1. Power is developed by the system at a rate of 2.2 MW. Process steam leaves at location 2, and hot water for other process uses leaves at location 3. Evaluate the rate of heat transfer, in MW, between the system and its surroundings. Let g 5 9.81 m/s2 .
