A solar thermal engine operating between 20 degrees celsius and 200 degrees celsius has efficiency equal to one-half of the Carnot efficiency. This engine needs to provide 5 kW power to drive a water pump. If the collector can absorb 50 percent of the solar insolation falling on the collector surface, determine the required area of the solar collector for a location where the averaged solar insolation is 800 W/m2.
