This page calculates the temperature rise across a multilayer cylinder for a heat load (Q) applied to its inner surface at r0 and flowing to the outer surface.

Define the cylinder's inside radius, length and the heat load conducted through the layers. This page will calculate the temperature rise between the inner and outer surfaces of this cylinder stack. For a positive heat load T0 > Tn and for a negative heat load Tn > T0.
