Saturated air at 20°C at a rate of 70 m3/min is mixed adiabatically with the outside air at 35°C and 50% RH at a rate of 30 m3/min. Assuming that the mixing process occurs at a pressure of 1 atrn, determine the specific humidity, the relative humidity, and dry bulb temperature and volume flow rate of the mixture. B. The psychrometry is (a) study of cooled air (b) study of hot air (c) study of moist air (d) none of the above
