Hello all;

i have a model of pipe made from copper in a cold environment and hot air inlets with "0.1" m/s at "50" Celsius , my goal is to calculate the condensation rate in pipe (g/h) when there is 1% mass fraction of water in the air at inlet.

- i  want to use the tracer study to calculate it .

Note; the water that doesn't condensate exits the pipe.

the project is defined with boundary conditions successfully, but i cant get the accurate results for the my goal.

  Could you Advise ?

Regards;
