A water heater uses 100?kW to heat 60 gallons of liquid water from an initial temperature of 20°C. The average density and specific heat of the water are 970?kg/m3 and 4.18?kJ/kg•K, respectively. According to the service restrictions of the ASME Boiler and Pressure Vessel Code (ASME BPVC.IV-2015, HG-101), water heaters should not be operating at temperatures exceeding 20°C at or near the heater outlet. Determine the heating duration such that the final water temperature that would exit the water heater would be in compliance with the ASME Boiler and Pressure Vessel Code.
