Refrigerant 134a is the working fluid in a solar power plant operating on a Rankine cycle. Saturated vapor at 60 degree Celsius enters the turbine, and the condenser operates at a pressure of 6 bar. The rate of energy input to the collectors from solar radiation is 0.4 kW per m2 of collector surface area. Determine the minimum possible solar collector surface area, in m2, per kW of power developed by the plant.
