Heat Penetration

Heat penetration is the depth at which heat from any heat source dissipates into a source.    

 

Heat penetration Formula
\(\large{ d = k \; \sqrt{ a \; t }  }\)
Symbol	English	Metric
\(\large{ d }\) = penetration depth	\(\large{in}\)	\(\large{mm}\)
\(\large{ k }\) = thermal conductivity	\(\large{\frac{Btu-ft}{hr-ft^2-F}}\)	\(\large{\frac{W}{m-K}}\)
\(\large{ \alpha }\) (Greek symbol alpha) = thermal diffusivity	\(\large{\frac{ft^2}{sec}}\)	\(\large{\frac{m^2}{s}}\)
\(\large{ t }\) = time	\(\large{sec}\)	\(\large{s}\)
