Heat Penetration

Written by Jerry Ratzlaff on . Posted in Thermodynamics

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

 

Heat penetration Formula

\(\large{ d = k \; \sqrt{ a \; t }  }\)   

Where:

 Units 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 \(\large{sec}\) \(\large{s}\)
