a. Determine the mass flow rate for the working fluid of the
Rankine cycle, in lb/h.
b. Devise and evaluate an exergetic efficiency for the overall
cogeneration system.
In a cogeneration system, a Rankine cycle operates with steam entering the turbine at 800 lbp/in.2,700°F, and a condenser pressure of 180 lbf/in. The isentropic turbine efficiency is 90%. Energy rejected by the condensing steam is transferred to a separate process stream of water entering at 250°F, 140 lbf/in.- and exiting as saturated vapor at 140 Ibf/in. The mass flow rate of the process stream is 49,000 lb/h. Let To = 70°F, PO = 14.7 lbf/in. 2 2 =
