This page calculates the temperature on one side of an
isothermal (constant temperature) multilayered plate or wall. You must define
the heat load (Q) conducted through the layers as well as
the temperature on one side of the plate (T_{1}) .The temperature on the
opposite side of the plate is calculated. For each layer you must define the layer
thickness (t_{i}) as well as the layer conductivity k_{i}.

The temperature (T_{n}) is calculated as:

T_{n} =

Where *T _{1}* is the known surface temperature,

Positive values of heat (Q) result in T_{n} being
hotter than T_{1}. Negative values of heat (Q) result in T_{n}
being cooler than T_{1}.
