Where:

Q = Rate of Steady State Heat Conductivity (W)
S = Conduction Shape Factor (m) which has the dimension of length, and k is the thermal conductivity of the medium between the surfaces. The conduction shape factor depends on the geometry of the system only.
k = Thermal Conductivity (W/m · °C)
T₁ = Temperature (°C)
T₂ = Temperature (°C)
D = Diameter (m)
L = Length (m)
z = Distance (m)
