Two airstreams are mixed steadily and adiabatically. The first stream enters at 35°C and 30 percent relative humidity at a rate of 15 m3/min, while the second stream enters at 12°C and 90 percent relative humidity at a rate of 25 m3/min. Assuming that the mixing process occurs at a pressure of 90 kPa, determine the specific humidity, the relative humidity, the dry-bulb temperature, and the volume flow rate of the mixture. Use data from the tables.

a)The specific humidity is kg H2O/kg dry air.
b)The relative humidity is %.
c)The dry-bulb temperature is °C.
d)The volume flow rate of the mixture is m3/min.
