< 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 60%. 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 lbf/in.2 The mass flow rate of the process stream is 49,000 lb/h. Let To = 70°F, Po = 14.7 lb/in.² Step 1 Determine the mass flow rate for the working fluid of the Rankine cycle, in lb/h. mcycle = i lb/h
