There is an air flow with a temperature of 32.0°C, and it is humidified by making it flow over a container filled with water and whose length is 1.2 m. The temperature at the air-water interface is 20.0 °C. If the initial humidity of the air is 25.0% and its speed is 0.15 m/s. You are asked to determine: a. The mass transfer coefficient. b. The rate of evaporation of water per unit width of the container. For this purpose, you must use the following empirical correlation: Sh = 0.664Re^0.5Sc^0.333 - Sherwood number (Sh) - Schmidt number (Sc) Psat(20.0°C) = 0.02308 atm Psat(32.0°C) = 0.04696 atm R= 0.082 atm I/Kmol Dwater in air = 2.77-10-5 m^2/s NH20: it is expressed in mol/m^2s

Question

There is an air flow with a temperature of 32.0℃, and it is humidified by making it flow over a container filled with water and whose length is 1.2 m. The temperature at the air-water interface is 20.0 ℃. If the initial humidity of the air is 25.0% and its speed is 0.15 m/s.

You are asked to determine:

a. The mass transfer coefficient.
b. The rate of evaporation of water per unit width of the container.
For this purpose, you must use the following empirical correlation:
Sℎ = 0.664Re^0.5Sc^0.333
- Sherwood number (Sh)
- Schmidt number (Sc)
Psat(20.0℃) = 0.02308 atm
Psat(32.0℃) = 0.04696 atm
R= 0.082 atm l/Kmol

Dwater in air = 2.77 ∙ 10−5 m^2⁄s
 
NH2O: it is expressed in mol/m^2s
