Moisture (GPM) required to lower inlet temperature

Data:
    Temperature Dry Bulb: 110°F
    Temperature Wet Bulb: 70°F
    Turbine Air Flow: 745,388 ft3/min

From Table (See Above):
    Humidity Ratio: 64 grains/(lb dry air)
    Specific Volume: 13.75 ft3/(lb dry air)

Calculation:

(745,388 ft3/min)(64 grains/lb. of dry air)	= 59.7 GPM 60 GPM
(7000 grains/lb. of water)(13.75 ft3/lb. of dry air)(8.3lbs/gallon)
