An engineer is developing an electric water heater to provide a continuous ("on demand") supply of hot water. One trial design is shown in the figure. (Figure 1) Water is flowing at the rate , the inlet thermometer registers , the voltmeter reads , and the ammeter reads current . Then the power (i.e., the heat generated per unit time by the heating element) is . Assume that the heat capacity of water is and that the heat capacity of the heater apparatus is . When a steady state is finally reached, what is the temperature reading of the outlet thermometer? What is the power at which the heater operates?
