I have is a tungsten wire heated in different temperatures in the form of flowing electric current. I want to know the heat-transfer coefficient of the air in various pressures. Does it depend on the temperature of the body with which the air exchanges heat?
Have an insight or suggestion?

27 February 2009 at 1:29pmResistance heating with an unsheathed element typically will involve both radiation and convection components. Please refer to Chapter 30 of “Process Heat Transfer” by Hewitt, Shires & Bott (Begell House Publishers, 1994).
