A water heating system has a fully mixed tank of capacity 400 liters. The tank is located in a building having a temperature of 19°C. The collector area is 5.0 m². The tank area-loss coefficient product (UA), = 0.81 W/°C, Fr(Ta) = 0.76, and FRUL = 4.80 W/m² °C. In a particular hour when the ambient temperature is 12°C, the radiation on the plane of the collector is 18.0 MJ. The load on the system is 5.20 MJ. If the tank temperature is 43°C at the beginning of the hour, estimate the temperature at the end of the hour. A water heating system has a fully mixed tank of capacity 400 liters.
