Question:

A rigid tank contains 20 kg of liquid water at 100 kPa and 25oC. Heat at a rate of 10 kW is transferred into the tank from a source at 1000 K. Determine (a) the rate of energy transfer from the heating source, (b) the rate of increase of temperature and (c) the rate of energy change (dΦ/dt) of the water in the tank. Assume the atmospheric temperature to be 300 K.
