This value does not vary as the result of temperature. RH is expressed as a percentage and varies with the temperature of the air. As heat is removed from an air mass, the AH remains the same as the RH increases. The wet bulb is dependent on the moisture content of the air. Wet bulb temperature is taken by attaching a piece of wetted gauze around the thermometer bulb.
Humidity makes the wet bulb temperature vary.
The lower the humidity, the greater the rate of evaporation. The increased cooling effect causes a reduction in temperature. Enthalpy is a measure of the thermal properties of an air mass. At the dew point, condensation will occur. Determine the following loads.
