An Electric Water Heater
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 F, the inlet
thermometer registers T₁, the voltmeter reads V, and the ammeter reads current I. Then the power
(i.e., the heat generated per unit time by the heating element) is VI.
Assume that the heat capacity of water is C and that the heat capacity of the heater apparatus is Ch-
Part A
When a steady state is finally reached, what is the temperature reading T₂ of the outlet thermometer?
