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?

Re: What is the heat-transfer coefficient in various pressures?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).
