Solar radiation is incident on a flat-plate collector at a rate of 880 W/m2. The product of the transmissivty of glazing and the absorptivity of absorber plate is 0.82. The collector has a surface area of 33 m2. This collector supplies hot water to a facility at a rate of 6.3 L/min. Cold water enters the collector at 18oC. If the efficiency of this collector is 70 percent, determine the temperature of hot water provided by the collector.
