Air temperature drop in an duct.

[mattstandhaven]

Good morning all,

I need to try and determine the expected temperature drop of air in a duct/pipe over a set distance.

Specifically the pipe is 60mtr Long & 1400mmD x6mm stainless steel the air enters at 95degC with a velocity of 7.9m/s

The pipe is un-insulated as we actually need to lose heat and the pipe is external and exposed to the elements so a summer condition is our worse case scenario.

I don't need to be super accurate but need to know roughly what temperature the air exits at.

Any ideas?
