Homework Help: Temperature of Nitrogen in a Pipe

  1. Jun 29, 2008 #1
    Hi, i am on work experience and they have given me a short task which is sort of the next step up from work i have done previously. Can anyone help me with the following:-

    Vessel containing nitrogen at 50 oC

    Nitrogen is pumped along a 30m length of pipe at a flow rate of 1.5 litres per minute

    pipe line is at ambient temp 20 oC

    I need to find the temperature of the Nitrogen upon it reaching the end of the pipe at 30m

    I have calculated and gathered the following info -

    pipe OD - 0.00635m
    pipe ID - 0.00457m
    Specific Heat Ration of Nitrogen (k) - 1.4
    Absolute Preesure through pipe - 9bar
    Density of nitrogen at 9bar - 9.47748 kg/m3

    I'm not exactly sure how to start this?? But i have looked through some books and believe i need to work out the velocity first?? Any help would be greatly appreciated.

    Please ignore this post and refer to the later post on 01/07/2008 named "Thermodynamics Change in Gas Temperature along pipe" which is an attempt at the question and should be a clearer.
