Temperature Differential

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Temperature differential is the difference between two specific temperature points of a volume at a given time in a system.


\(\Delta T = T_h \;- \; T_l\)

\( \Delta T =   \frac {\dot {Q}_t     l}   {k_t}       \)


\(\Delta T\) or \(TD\) = temperature differential

\(T_h\) = high temperature

\(T_l\) = low temperature

\(\dot {Q}_t\) = heat transfer rate

\(l\) = length

\(k_t\) = thermal conductivity constant

Solve for:

\( l = k_t \frac {\Delta T} {\dot {Q}_t}   \)
