In a solar water heater, energy from the Sun is collected by water which circulates via tubes in a rooftop collector. The solar radiation enters the collector via a transparent cover and warms the water in the tubes; this water is pumped into a holding tank. Suppose that the efficiency of the overall system is around 13.0% (which is 87% of the incident solar energy is lost from the system). What collector area (in square meters) is essential to increase of the temperature 240 L of water in the tank from 22°C to 35°C in 2.8 h if the intensity of incident sunlight is 600 W/m2? The specific heat of water is around 4186 J/kg•K. The density of water is around 1.00 g/cm3.
