A stream of outdoor air is mixed with a stream of return air in an air conditioning system that operated at 101.3 kPa barometric pressure. The flow rate of outdoor air is 1.6 kg/s, and its conditions are 32°C DB, 24°C WB, and 0.0154 kg/kg d.a. The flow rate of return air is 2.4 kg/s, and its conditions are 23°C DB, 50% RH, and 0.00875 kg/kg d.a. Determine the enthalpy of the mixture. a. 50.67 kJ/kg d.a. b. 53.21 kJ/kg d.a. c. 55.88 kJ/kg d.a. d. 57.94 kJ/kg d.a.
