Steam enters a counterflow heat exchanger operating at steady state with a specific enthalpy of 2,367 kJ/kg and exits as liquid water with a specific enthalpy of 275 kJ/kg. A separate stream of air with a mass flow rate of 9.4 kg/s enters at 40°C and exits at 90°C. For the air as an ideal gas, use a specific heat of c, = 1.005 kJ/kg-K. Kinetic and potential energy effects are negligible. What is the mass flow rate of the steam thru the heat exchanger? air in air out water out steam in
