A solar-powered Rankine cycle power plant uses 18.5 × 103 m2 of solar collectors. Refrigerant-22 is used as the working fluid at a flow rate of 1.00 kg/s and is transformed to a saturated vapor in the solar collectors (which function as the boiler) at a temperature of 40.0°C.
The condenser for the system operates at 20.0°C and has a quality of 0.00 at the exit. The pump and prime mover isentropic efficiencies are 65.0% and 75.0%, respectively.
Determine the prime mover power output and system thermal efficiency when the incident solar flux is 8.00 W/m2 .
