In solar water heater, energy from sun is gathered by water that circulates through the tubes in a rooftop collector. The sun heated water is pumped to a water container. Assume the efficiency of the system to be 20%. What collector area is needed to raise the temperature of 200 litre of water in a tank from 20∘C to 40∘C in 1.0 hours when the intensity of the sunlight is 700 W/m^2?
