Using psychrometric chat to answer the questions below:

15 m3/min humid air is to be cooled using an air conditioning unit. The inlet air is at 35 °C and 60% relative humidity and should be cooled to 18 °C, at which point it will be saturated.

a) Below which temperature will condensation start occurring?

b) How much water will have condensed if cooled to 18 C (mw,out)?

c) Determine the heat removal, Qout, using the first law of thermodynamics.

Humid air is enclosed in a 5.00-liter flask at 40.0°C. The flask is slowly cooled. When the temperature reaches 20.0°C, drops of moisture become visible on the flask wall. Although the pressure in the flask changes when the temperature drops, it remains close enough to 1 atm for the psychrometric chart to provide a close representation of the behavior of the system throughout the process. Use a psychometric chart to determine the relative humidity, absolute humidity, and wet-bulb temperature of...
