In a cogeneration system, a Rankine cycle operates with steam entering the turbine at 800 lb-/in.2, 700°F, and a condenser pressure of
180 lb/in.² The isentropic turbine efficiency is 80%. Energy rejected by the condensing steam is transferred to a separate process
stream of water entering at 250°F, 140 lb-/in.² and exiting as saturated vapor at 140 lb/in.² The mass flow rate of the process stream
is 48,000 lb/h. Let To = 70°F, po = 14.7 lb//in.²
