Previous blogs have talked about heat conductivity in very general terms to produce a foundation for this somewhat more technical view for those of you who like formulas and numbers. Conductive heat transfer can be expressed with “Fourier’s Law” q = k A dT / s where q = heat transfer (W, J/s, Btu/hr) A …
Heat conductivity is a measure of the ability of a material to transfer heat within itself. For example, if you heat one end of a short piece of copper wire, the heat is quickly distributed throughout the wire by conduction. This can be easily demonstrated using a short piece (1 to 2 inches) of heavy gage …
Temperature has been identified as one of the important variables in cleaning – arguably the most important. So I thought it might be worth some time to develop a little understanding of heat – – especially how it is generated and transmitted. Heat is a form of energy. The amount of heat contained in an object …
