How to Determine the Temperature and Water Mass Flow in an Evaporative Cooler
What are the key parameters needed to calculate the temperature of the air leaving an evaporative cooler and the mass flow of water added in the cooler?
Calculating the Temperature of Air Leaving the Cooler
Calculating the Mass Flow of Water Added in the Cooler
The mass flow of water added in the cooler can be determined by analyzing the change in specific humidity and the amount of water vapor absorbed by the air during the adiabatic saturation process. This calculation involves understanding the mass balance of water in the system and the change in specific humidity of the air.
Step 1: Calculate the change in specific humidity (delta omega) by subtracting the initial specific humidity (omega1) from the final specific humidity (omega2).
Step 2: Determine the mass flow rate of water added in the cooler by multiplying the change in specific humidity (delta omega) by the mass flow rate of dry air (1000 CFM).
By following these steps and calculations, we can determine both the temperature of the air leaving the evaporative cooler and the mass flow of water added in the cooler accurately.
