An engineer is developing an electric water hearer to provide a continuous supply of hot water. One trial design is shown in Fig. 17.34. Water is flowing at the rate of 0.500 kg/min, the inlet thermometer registers18.0°C, the voltmeter reads 120 V, and the ammeter reads 15.0 A [corresponding to a power input of (120 V) X (15.0A) = I800Wj.
(a) When a steady state is finally reached, what is the reading of the outlet thermometer?
(b) Why is it unnecessary to take into account the heat capacity me of the apparatus itself?
