    Heat Loss in gas flow through Pipe

    Hi,

    I'm trying to work out a formula for calculating the heat loss of hot air flowing through a pipe in cold air, so that eventually I can spec the length of pipe needed.
    It's been a while since I'v done any thermodynamics so some help would really be appreciated. I've summarised the problem in the image bellow.




    I thought about doing an iterative solution like bellow, but am struggling to understand which formulas I should be combining to account for heat loss to environment and heat flow along pipe.




    Thanks,


    Matt

    Tell me and I forget. Teach me and I remember. Involve me and I learn.
