An electric water heater supplies hot water at 200 kPa, 80oC at a flow rate of 8 L/min while consuming 32 kW of electrical power as shown in the accompanying animation. The water temperature at the inlet is 25oC, same as the temperature of the surroundings. Using the SL (solid/liquid) model for water and neglecting kinetic and potential energy changes, determine.
(a) The rate of heat loss to the atmosphere.
(b) The energetic efficiency.
(c) The rate of entropy generation in the heater's universe. Assume no pressure loss in the system.
