Air at 14.7 psia, 50°F (DB), and 60% relative humidity is first heated to 110°F (DB) and then humidified by introducing water using an “air washer.” The air leaves the humidifying section at 70°F (DB). Plot the process on a Psychrometric Chart and determine:
a) The amount of heat transfer to the air [Btu/lbma]
b) The amount of water added to the air [lbmH2O(v)/lbma]
c) The Relative Humidity [%], wet-bulb temperature [°F], and Humidity Ratio [lbmH2O(v)/lbma] of the final state
