A solar collector receiving solar radiation at the rate of 0.6 kW/m2 transforms it to the internal energy of a fluid at an overall efficiency of 50%. The fluid heated to 350 K is used to run a heat engine which rejects heat at 313 K. If the heat engine is to deliver 2.5 kW power, then the minimum area of the solar collector required would be A. 8.33 m2 B. 16.66 m2 C. 39.68 m2 D. 79.36 m2
