Homework Help: Heat Transfer Question

  1. Jun 29, 2006 #1
    I was wondering if anyone knew the heat transfer coefficient of a thin steel sheet on top of water. It is vital that I find this answer because it is a major part of my research. I found one formula which stated that the U value could be found by using the formula 1/U= x1/k1 + x2/k2. I wanted to know if this formula was correct or if not, what would be a better formula to use. Thanks for the help.

    That depends on whether or not the water is flowing.

    Static water would involve pure heat conduction, whereas flowing water would involve convection as well as conduction.
