Temperature Differential

Temperature differential (\(\Delta T\) or \(TD\)) is the difference between two specific temperature points of a volume at a given time in a system.

Temperature Differential Formula

\(\Delta T = T_h \;- \; T_l\)          \(temperature \; differential  \;=\;   high \; temperature   \;- \;  low \; temperature  \)

\( \Delta T =   \frac {\dot {Q}_t     l}   {k_t}    \)          \( temperature \; differential  \;=\;   \frac {  heat \; transfer \; rate  \;\;x\;\;   length }   { thermal \; conductivity \; constant  }  \)

Where:

\(\Delta T\) 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:

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