Two airstreams are mixed steadily and adiabatically the first stream enters at 32°c and 40 percent relative humidity at a rate of 20 m/min, while the second stream enters at 12°c and 90 percent relative humidity at a rate of 25 m/min assuming that the mixing process occurs at a pressure of 1 atm determine a) the specific humidity b) the relative humidity c) the dry-bulb temperature d) the volume flow rate of the mixture.
