Conduction as heat transfer takes place if there is a temperature gradient in a solid or stationary fluid medium.
Conductive heat transfer can be expressed with "Fourier's Law"
q = (k / s) A dT
= U A dT (1)
where
q = heat transfer (W, J/s, Btu/hr)
k = Thermal Conductivity of material (W/m K or W/m oC, Btu/(hr oF ft2/ft))
s = material thickness (m, ft)
A = heat transfer area (m2, ft2)
U = k / s
= Coefficient of Heat Transfer (W/(m2K), Btu/(ft2 h oF)
dT = t1 - t2
= temperature gradient - difference - over the material (oC, oF)
