In a solar water heater, energy from the Sun is gathered by water that circulates through tubes in a rooftop collector. The solar radiation enters the collector through a transparent cover and warms the water in the tubes; this water is pumped into a holding tank. Assume that the efficiency of the overall system is 15.0% (that is, 85% of the incident solar energy is lost from the system). What collector area (in square meters) is necessary to raise the temperature of 440 L of water in the tank from 24°C to 36°C in 2.6 h when the intensity of incident sunlight is 610 W/m2? The specific heat of water is 4186 J/kg·K. The density of water is 1.00 g/cm3
