Find Outlet Temp of Cold Stream of Counterflow in Double Pipe Heat Exchanger

  1. Oct 20, 2009 #1
    Given the mass flow, Cp, temp of the inlet streams of both hot and cold streams.
    As well as being given the inner pipe diametre of the double pipe heat exchanger.
    Also knowing the setting is at counterflow and that the overall heat transfer coefficient and that the temp difference between the two liquids is no less than 10C at any point in the exchanger.

    How would you go about finding the outlet temp of the cold stream?

    What equations would you use?
