General thermal conductivity
Input(s)
Q: Heat Flow Rate (BTU/s)
L: Length (ft)
A: Area \(\left(\mathrm{ft}^{2}\right)\)
\(\partial T\): Temperature Difference \((\mathrm{K})\)
Output(s)
k: Thermal Conductivity (BTU/ft s K)
Formula(s)
\[
\mathrm{k}=\frac{\mathrm{Q} * \mathrm{~L}}{\mathrm{~A} * \partial \mathrm{T}}
\]
