Mean heat transfer coefficient for 304 stainless steel

[peter6]

I'm looking for the mean coefficient of heat transfer (not heat conductivity) for the 304 stainless steel. It is given in: w/m2°K or Kcal/m2°C or BTU/ft2°F.

Please advice.

Thanks

Error: insufficient data. Please describe fluid transferring heat, including velocity and mean temperature.

Are you looking for a U-value, like the ones used in insulation and building material ratings? Don't have any data on stainless, but there is a stinless steel forum on this web site. I'm sure they can help you.

Peter6, What btrueblood is saying is heat transfer coefficient is the expected rate of heat transfer across an interface between one material and another. It is not a property of a material.

Water flooding a steel surface at some rate will result in a heat transfer of Btu/ft2/F. It is process dependent on rate of flooding and whether it is laminar, turbulent, etc.

Example: Hot air blowing on a brick wall will have a different HTC than water spraying on a brick wall, so you can't ask for the HTC of brick. Got it?

Beside what BigInch tells you, kindly note that, except for the first units, your following units for the heat transfer coefficient are incorrect because they lack the time element. They should be, for example: kcal/(h.m[sup]2[/sup].K), or BTU/(ft[sup]2[/sup].h.[sup]o[/sup]F).
