Sem2 Wks6-8 Part:3 Heat exchanger Steam enters a heat exchanger operating at steady state at 2.5 bar with a specific enthalpy of 2078 kJ/kg and exits at the same pressure as a saturated liquid. The steam mass flow rate is 1.58 kg/min. A separate stream of air with a mass flow rate of 53.5 kg/min enters at 24.1 "Cand exits at 67.2°C. The ideal gas model with c, = 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.
