Heat Transfer Through a Cylinder

  1. May 16, 2007 #1
    The problem is about a cylinder with 3 mm thickness in the walls, roof, and ceiling. The walls, roof, and ceiling also have a k value of .0042 w/mk. Inside the cylinder is 64 degrees Celsius and outside its 22 degrees Celsius. The air outside the cylinder has a heat transfer coefficient of .3 W/m^2K. I have to calculate the heat loss for this cylinder. My question is, how do I add the resistances for the walls, ceiling/base, and air? Would it be delta T/(Rwall, Rceiling/base, Rair(wall), Rair(base/ceiling))?

    Can you post the actual problem statement?

    I think if you draw a thermal circuit, it will give you a good map to solve the problem.
