Air at 1 atm, 36C, 20% relative humidity enters an evaporative cooler at 4 m^3/min. Sufficient water at 20C is added to lower the air temperature to 25C. Using the psychrometric chart, determine the following:

a) the inlet humidity ratio

b) the outlet humidity ratio

c) the dry air mass flow rate (kg/min)

d) the spray water mass flow rate (kg/min)
