Thermal Conductivity Calculation  

Thermal Conductivity Constant :
K_{T} = q_{x}x/ ΔT
Temperature Differential :
ΔT = q_{x}x/ KT
Distance or Length :
x = K_{T} * ΔT/q_{x}
Where,
q_{x} = Heat Transfer Rate or Flux,
K_{T} = Temperature Differential,
ΔT = Thermal Conductivity Constant,
x = Distance or Length.
Example:
Calculate the Thermal Conductivity by the given details.
Calculate = Heat Transfer Rate or Flux
Thermal Conductivity Constant (KT) = 25 calorie/degreecms
Temperature Differential (ΔT) = 15
Distance or Length(x) = 10 cm
Solution:
Apply Formula:
q_{x} =K_{T}*ΔT/x
Heat Transfer Rate or Flux (q_{x}) = 37.5 calorie/cm2s
