Water flows steadily into a well-insulated electrical water heater (see Anim. 4- 1-1) with a mass flow rate of 1 kg/s at 100 kPa, 25oC. Determine:
The rate of entropy generation in the water heater's universe if the water becomes saturated (liquid) at the exit. Assume no pressure loss, neglect changes in ke and pe, and use the SL model (use cv = 4.184 kJ/kg.K for water). The ambient atmospheric conditions are 100 kPa and 20oC.
