Saturated steam at 200 kPa, which has a specific enthalpy (h) of 2707 kJ/kg is expelled from a pressure cooker at a rate of 0.1 kg/s. Determine the rate of heat transfer necessary to maintain a constant stored energy E in the cooker. Assume that there is sufficient liquid water in the cooker at all time to generate the saturated steam. Neglect kinetic and potential energy of the steam.
