One thousand cfm of air with a temperature of 100 F db and 10 percent relative humidity (RH)

at a barometric pressure of 14.7 psia is humidified under adiabatic steady-flow conditions to 40 percent relative humidity with saturated vapor at 14.7 psia. Use the program PSYCH to find:

(a) the final temperature of the air,

(b) the mass of water vapor added to the air, and

(c) the leaving volume flow rate.
