Temperature Differential

Written by Jerry Ratzlaff on . Posted in Thermodynamics

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

\(\large{ \Delta T = T_h \;- \; T_l  }\)         

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

Where:

\(\large{ \Delta T }\) = temperature differential

\(\large{ l }\) = length

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

\(\large{ T_h }\) = high temperature

\(\large{ T_l }\) = low temperature

\(\large{ k_t }\) = thermal conductivity constant

Solve for:

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