The figure below provides steady-state operating data for a cogeneration cycle that generates electricity and provides heat for campus buildings. Steam at 1.5 MPa, enters a two-stage turbine (isentropic) with a mass flow rate of 1 kg/s. A fraction of the total flow, 0.15, is extracted between the two stages at 0.2 MPa to provide for building heating, and the remainder expands through the second stage to the condenser pressure of 0.1 bar. Condensate returns from the campus buildings at 0.2 MPa and passes through a trap into the condenser, where it is reunited with the main feedwater flow. Saturated liquid leaves the condenser ato i bar Determine Draw the T-S diagram for the cycle and determine (20 points) a) the rate of heat transfer to the working fluid passing through the boiler, in kW. (15 points) b) the net power developed, in kW.
