6/06/2016 · In this video, we derive the formula for specific volume as a function of dry bulb temperature, total pressure, and the specific or absolute humidity ratio.... Air Density and Specific Weight Equations and Calculator - The density of air, ρ (Greek: rho) (air density), is the mass per unit volume of Earth's atmosphere. Air density, like air pressure, decreases with increasing altitude. It also changes with variation in temperature or humidity.

## How To Find Specific Volume Of Air

If dry air is about 1kg/m3 and the water vapour has displaced some of the dry air molecules then the SHC of the humid air (dry air + water vapour) is going to be less than 1.300kJ/kg.K. To convert H2O from liquid to gas (water to water vapour) requires 2.3kJ/g of latent heat which is more energy than is required to raise 1kg of water 1K.

- Air Density Calculator. Air density is the mass per unit volume of Earth's atmosphere. When the altitude increases, density of air decreases. It also changes with the variation in temperature or humidity.
- b) In the second case, the volume of the tank is now 400-L or 0.4 m3, and the specific volume of the water in the tank is 0.2 m 3 /kg. Repeating the same process, we find that this becomes single -
- where v denotes specific volume; u is specific internal energy; R is the gas constant for air. At low temperatures the air is liquified. The normal (at 0.1013 MPa) boiling (condensation) temperature of the oxygen is equal— 183°C, that of the nitrogen -195.8°C.
- Air Velocity is measurement of the rate of displacement of air or gas at a specific location. Air velocity (distance traveled per unit of time) is usually expressed in Linear Feet per Minute (LFM). By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time. Volume flow is usually measured in Cubic Feet per
