Variables Used
Bulk Gas Temperature - Bulk gas temperature is adiabatic mixing of the gas from a given cross section of duct will result in some equilibrium temperature that accurately reflects average temperature of the moving fluid.
Liquid Phase Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - Liquid Phase Heat Transfer Coefficient is the heat transfer in liquid per unit area in kelvin.
Inside Temperature - (Measured in Kelvin) - Inside Temperature is the temperature of air present inside.
Liquid layer temperature - Liquid layer temperature is defined as the temperature of the flowing liquid layer in dehumidification.
Enthalpy of Evaporation - (Measured in Joule per Kilogram K) - 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.
Gas Phase Mass Transfer Coefficient - (Measured in Mole per Second Square Meter) - Gas phase mass transfer coefficient is a diffusion rate constant that relates the mass transfer rate, mass transfer area, and concentration change as driving force.
Absolute Humidity of Air(tg) - Absolute Humidity of Air(tg) at the initial air temperature.
Absolute Humidity (ti) - Absolute humidity (ti) is the quality of water vapor in the wet air of unit volume at temperature ti.

STEP 1: Convert Input(s) to Base Unit
Liquid Phase Heat Transfer Coefficient: 10.8 Watt per Square Meter per Kelvin --> 10.8 Watt per Square Meter per Kelvin No Conversion Required
Inside Temperature: 353 Kelvin --> 353 Kelvin No Conversion Required
Liquid layer temperature: 20 --> No Conversion Required
Enthalpy of Evaporation: 90 Joule per Kilogram K --> 90 Joule per Kilogram K No Conversion Required
Gas Phase Mass Transfer Coefficient: 90 Mole per Second Square Meter --> 90 Mole per Second Square Meter No Conversion Required
Absolute Humidity of Air(tg): 16 --> No Conversion Required
Absolute Humidity (ti): 50.7 --> No Conversion Required
Gas Phase Heat Transfer Coefficient: 40 Watt per Square Meter per Kelvin --> 40 Watt per Square Meter per Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Tg = (((h1*(ti-Tl))-(hfg*ky*(Yg-Yi)))/hg)+ti --> (((10.8*(353-20))-(90*90*(16-50.7)))/40)+353
Evaluating ... ...

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.
