I'm looking at the dynamic state of heat transfer through a concrete slab. Suppose heat is turned on at t=0 and the coils/tubing are 6 inches below the surface. Is there a formula or way of calculating the temperature at the surface at time = t?(adsbygoogle = window.adsbygoogle || []).push({});

I found a formula for thermal lag on wikipedia (without references -- can't find the source of the formula) for how long the time lag will be between the peak temperature on the bottom side of the slab and the peak temperature at the surface, but I would like to know the temperature profile as it rises to that peak at that point in time.
