# Thermal Conductivity Constant

## Thermal Conductivity Constant formula

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

### Where:

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

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

\(\large{ l }\) = length

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