Water is the working fluid in a cogeneration cycle that generates electricityand provides heat for campus buildings. Steam at 2 MPa, 320°C, expands through a two-stageturbine. Some steam is extracted between the two stages at 0.15 MPa to provide 10 6 kJ/hr for heating, and the remainder expands through the second stage turbine to the condenser pressure of 0.06 bar. The net power developed by the cycle is 600 kW. Condensate returns from the campus buildings (process heater exit) at 0.1 MPa, 60°C and passes through a throttling valve into the condenser, where it is reunited with the main feed-water flow. Saturated liquid at 0.06 bar leaves the condenser. Each turbine stage has an isentropic efficiency of 80%, and the pumping process can be considered isentropic. Determine:
a) The mass flow rate of steam into the first turbine stage, in kg/hr.
b) The heat transfer rate to the working fluid passing through the boiler, in kJ/hr.
c) The rate of heat transfer to the cooling water passing through the condenser
