Saturated liquid water flows steadily into a well-insulated electrical water heater with a mass flow rate (m˙) of 1.00 kg/s at 100 kpa and the heater turns water into saturated vapor at the exit.

assume no pressure loss, neglect changes in ke and pe, and use the pc model. the ambient atmospheric conditions are 100 kpa and 20∘c.

part a) determine the electrical power consumption.(in kw)

part b) determine the rate of entropy generation in the water heater’s universe (in kw/k)
