Web2. Specific Volume and Density. Air specific volume is measured in cubic feet per pound (ft³/lb). This is essentially the amount of space air occupies per pound of weight. The denser the air (humid air vs. dry air) the lower the specific volume. 3. Enthalpy. Enthalpy is the measure of heat energy (represented by the variable "h"). WebAs the name implies, relative humidity is a measure of how much moisture is present compared to how much moisture the air could hold at that temperature. Relative humidity, which is expressed as a percent, is given in weather reports. tandon hospital agra
