How to Calculate Vapour Density?
Vapour Density calculator uses vapor_density = (Specific Humidity*(Total pressure of moist air-Pressure of water vapour))/(287*Dry Bulb Temperature) to calculate the Vapor density, The Vapour Density formula calculates the vapor density which is the mass of water vapor present in 1 cubic meter of dry air. Vapor density is denoted by ρ_{v} symbol.
How to calculate Vapour Density using this online calculator? To use this online calculator for Vapour Density, enter Specific Humidity (ω), Total pressure of moist air (p_{t}), Pressure of water vapour (p_{v}) & Dry Bulb Temperature (t_{d}) and hit the calculate button. Here is how the Vapour Density calculation can be explained with given input values -> 139.3728 = (1*(10000000-6000000))/(287*100).
