Steam enters a heat exchanger operating at steady state at 15 bar with a specific enthalpy of 1577 kJ/kg and exits at the same pressure as a saturated liquid. The steam mass flow rate is 1.38 kg/min. A separate stream of air with a mass flow rate of 28.6 kg/min enters at 32 °C and exits at 65.1 °C The ideal gas model with cp = 1.005 kJ/kg.K can be assumed for air. Kinetic and potential energy effects are negligible. a) Determine the quality of the entering steam: Submit part 2 marks Unanswered b) Determine the rate of heat transfer between the heat exchanger and its surroundings: kW.
