    Air temperature drop in an duct.

    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?
