What is humidification?

Humidification is the process in which the moisture or water vapor or humidity is added to the air. Common equipment used in this process is a humidifier. Dehumidification as the term suggests, is the opposite of humidification since dehumidification means removing the moisture from the air. Common equipment used in this process is a dehumidifier. Humidity is the presence of water vapor or moisture in the air, while relative humidity, on the other hand, is the comparison of the actual moisture or water vapor in the air vs. the total water vapor or moisture that the air can handle.

How to Calculate Gas constant of water vapor?

Gas constant of water vapor calculator uses Gas constant=(((Enthalpy of evaporation*(Partial pressure -Partial pressure))/((Temperature-Wet bulb temperature)*Density*Specific heat of air*Mean temperature*(Lewis Number^0.67)))) to calculate the Gas constant, The Gas constant of water vapor formula is defined as the energy and temperature scale values required for the humidification. Gas constant and is denoted by Rw symbol.

FAQ

What is Gas constant of water vapor?
The Gas constant of water vapor formula is defined as the energy and temperature scale values required for the humidification and is represented as Rw=(((hfg*(Pw-P∞))/((T∞-Tw)*ρ*cp*Tf*(Le^0.67)))) or Gas constant=(((Enthalpy of evaporation*(Partial pressure -Partial pressure))/((Temperature-Wet bulb temperature)*Density*Specific heat of air*Mean temperature*(Lewis Number^0.67)))). Enthalpy of evaporation is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas, Partial pressure of the water vapor at wet bulb temperature, Partial pressure of the water vapor in air is the pressure of water in the mixture of water and air, Temperature of the atmospheric air, Wet bulb temperature is the temperature of the wet bulb, The density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object. , Specific heat of air is the heat required to raise the temperature of a air by one degree to that required to raise the temperature of an equal mass of water one degree, Mean temperature is the mean value of all the observed temperatures and The Lewis number (Le) is a dimensionless number .
