Saturated air leaving the cooling section of an A. C system at 14 C° at a rate of 50 m'/min is mixed adiabatically with the outside air at 32 C° and 60 percent relative humidity at a rate of 20 m'/min. Assuming that the mixing process occurs at a pressure of 1 atm. Determine: 1-Humidity ratio 2-relative humidity 3-Dry-bulb Temperature 4-Volume flow rate of the mixture. B- A heating section consists of a 15 in-diameter duct that houses a 4 kW electric resistance heater. Air enters the heating section at 14.7 psia, 50 F, and 40 percent relative humidity at a velocity of 25 ft/s. Draw schematic of the system and complete the solution with units system given in question. Determine (a) the exit temperature, (b) the exit relative humidity of the air, and (c) the exit velocity.note that [1 °C=(F-32)/1.8] Saturated air leaving the cooling section of an A.
