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)

T_{1} = Temperature (°C)

T_{2} = Temperature (°C)

D_{1} = Diameter (m)

D_{2} = Diameter (m)
