A stream consisting of 35 m3 /min of moist air at 148C, 1

A stream consisting of 35 m3 /min of moist air at 148C, 1 atm, 80% relative humidity mixes adiabatically with a stream consisting of 80 m3 /min of moist air at 408C, 1 atm, 40% relative humidity, giving a single mixed stream at 1 atm. Using the psychrometric chart together with the procedure of 12.93, determine the relative humidity and temperature, in 8C, of the exiting stream.
