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 29.0% (that is, 71% of the incident solar energy is lost from the system). What collector area is necessary to raise the temperature of 430...
