Q5/A 400 m light-colored swimming pool is located in a normal suburban site, where the measured wind speed at 10 m height is 2 m/s. The water temperature is 25 °C, the ambient air temperature is 10 °C, and relative humidity is 60%. There are no swimmers in the pool, the temperature of the make-up water is 20 °C, and the solar irradiation on a horizontal surface for the day is 15 MJ/m²-d. Neglect heat losses due to evaporation and radiation. How much energy must the solar system supply (Qss) to the pool to keep its temperature to 25 °C? Take: a = Solar absorptance (a = 0.85 for light-colored pools; a = 0.90 for dark colored pools).
