At sea level conditions, 2000 cfm of outside air is entering a mixing box at 50°F dry bulb and 42°F wet bulb and mixes with 9000 cfm of return air which is at 80°F dry bulb and 70°F wet bulb. Determine the thermodynamic state of the mixed air and report the following for the mixed air: 1)Dry bulb temperature, 2) Wet bulb temperature, 3) Dew point temperature, 4) Relative humidity, 5) Humidity ratio, 6) Specific enthalpy, 7) Specific volume, 8) Density, 9) Mass flow rate. Show the process on a psychrometric chart.
