Mass velocity of air per unit area Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mass Velocity of Air = (Height*Gas Phase Mass Transfer Coefficient)/ln((Absolute Humidity of Air(ta)-Humidity of Air at Entry(t))/(Absolute Humidity of Air(ta)-Humidity of air at exit))
G = (Z*k_y)/ln((Ya-Y1)/(Ya-Y2))
This formula uses 1 Functions, 6 Variables

Functions Used

ln - The natural logarithm, also known as the logarithm to the base e, is the inverse function of the natural exponential function., ln(Number)

Variables Used

Mass Velocity of Air - Mass velocity of air is the amount of air travelling per unit area in a second.
Height - (Measured in Meter) - Height of the tower is the total length of the tower from the top to the bottom.
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(ta) - Absolute Humidity of Air(ta) at the final equilibrium air temperature.
Humidity of Air at Entry(t) - Humidity of Air at Entry(t) is the quantity of water vapor at wet air in the entrance of the tower.
Humidity of air at exit - Humidity of air at exit is the quantity of water vapor at wet air in the exit of the tower.

STEP 1: Convert Input(s) to Base Unit

Height: 0.05 Meter --> 0.05 Meter 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(ta): 8 --> No Conversion Required
Humidity of Air at Entry(t): 17 --> No Conversion Required
Humidity of air at exit: 15 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

G = (Z*k_y)/ln((Ya-Y1)/(Ya-Y2)) --> (0.05*90)/ln((8-17)/(8-15))

Evaluating ... ...

G = 17.9058561451559

STEP 3: Convert Result to Output's Unit

17.9058561451559 --> No Conversion Required

FINAL ANSWER

17.9058561451559 ≈ 17.90586 <-- Mass Velocity of Air

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 Mass velocity of air per unit area?
