A power plant based on the Rankine cycle is under development to provide a net power output of 10 MW. Solar collectors are to be used to generate Refrigerant 22 vapor at 1.6 MPa, 50°C, for expansion through the turbine. Saturated liquid leaves the condenser at 12 bar. Cooling water is available at 20°C and is only allowed to increase by 15°C. Assume ηT=85% and ηP=70%.
a.) Estimate the thermal efficiency of the power cycle.
b.) Determine the refrigerant flow rate, in kg/h.
c.) Determine the minimum possible cooling water flow rate, in kg/h.
