Two airstreams are mixed steadily and adiabatically. the first stream enters at 35°c and 30 percent relative humidity at a rate of 15 m/min, while the second stream enters at 12°g and 90 percent relative humidity at a rate of 25 mmin. assuming that the mixing process occurs at a pressure of 1 atm, determine the specific humidity, the relative humidity, the dry-bulb temperature, and the volume flow rate of the mixture.
