Heat transfer -- one-dimensional energy balance for the heating of a fluid...

  1. Oct 25, 2015 #1
    1. The problem statement, all variables and given/known data
    1. Perform a one-dimensional energy balance for the heating of a fluid through a hot pipe in order to develop a differential equation that governs the variation of the mean temperature of the fluid along the length pipe. The pipe has an inner diameter D and length L; its walls are kept at a constant temperature Tw. The fluid has a mean velocity v. The heat transfer coefficient h between the pipe wall and the fluid is constant, and the radial convective heat flux q is:

      q = hA(Tw − T ) where T is the mean temperature of the fluid.

      If the fluid has a mean inlet temperature To, solve the above differential equation to obtain an expression for the variation of the temperature with the distance x along the pipe. For this part of the problem, you can neglect the influence of conduction (i.e. assume k ≈ 0) and assume heat transfer along the pipe only occurs through convection.

    2. Relevant equations
    3. The attempt at a solution
    Any help will be greatly appreciated.
