How to find relative humidity in evaporative cooling ?
 
Hello, this is my first post here so please forgive me for any mistake.
My problem has a rectangular duct through which hot dry air is flowing and water is sprayed inside which evaporates and mixes with the air and cools the air.How can I find the change in relative humidity,dry and wet bulb temperature using fluent ?

If you are asking what the final bulk mixture is like, you can read it off a psychometric chart because you are basically asking what state the bulk component is in. It's like asking what density or temperature air is at if it is at a certain enthalpy and pressure.
