A 50-gallon electric water heater is used to heat tap water with an initial temperature of 15oC. The heating level is set at a maximum while several people are taking their showers. If the maximum heating level of the heater is 7.5kW of electricity and the water use rate is 3 gal/min, what is the temperature of the water exiting the heater? Assume that the system is at steady state and the heater is 100% efficient; that is it is...
