Humidity Ratio Calculator | Humidity Ratio Formula
This page covers Humidity Ratio Calculator and Humidity Ratio Formula. The calculator covers humidity ratio calculation by mass and by vapor partial pressure formula or equations.
Definition: The ratio of mass of water vapor present in the moist air with mass of dry air is known as humidity ratio of air. It can also be defined as follows.
Following are the two ways humidity ratio can be calculated.
➤By mass: It can be expressed using mass of water vapor present in humid air with mass of dry air.
➤By vapor partial pressure: It can be expressed using partial pressure of vapor in air with partial pressure of dry air.
Humidity Ratio Calculator by Mass
Following Humidity Ratio Calculator calculates humidity ratio using formula-1 provided below.
Example of humidity ratio calculator-1:
INPUTS : mass of water vapor = 100 , mass of dry air = 100
OUTPUTS: Humidity ratio (by mass) = 1 Kg/Kg
Humidity Ratio Formula by Mass
Following Humidity Ratio formula by mass is used for calculation in this calculator.
Humidity Ratio Calculator by vapor partial pressure
Following Humidity Ratio Calculator calculates humidity ratio using formula-2 provided below.
Example of Humidity ratio calculator-2:
INPUTS : Vapor partial pressure (Pw) = 2222 Pa, Atmospheric pressure (Pa) = 102325 Pa
OUTPUTS: Humidity ratio (by vapor partial pressure) = 0.0138 Kg/Kg
