Thermal conductivity, k, refers to the property of a material's ability to conduct heat. The SI unit of Thermal Conductivity is measured in watts per meter kelvin (W/ (m*K)). The quantity of heat that passes in unit time through unit area of a substance whose thickness is unity, when it's opposite faces differ in temperature by one degree is termed as thermal conductivity.
Heat Transfer Rate or Flux :
Thermal Conductivity Constant :
KT = qxx/ ΔT
Temperature Differential :
ΔT = qxx/ KT
Distance or Length :
x = KT * ΔT/qx
qx = Heat Transfer Rate or Flux,
KT = Temperature Differential,
ΔT = Thermal Conductivity Constant,
x = Distance or Length.
Thermal conductivity is termed as the property of a material that indicates its ability to conduct heat. Heat transfer across different materials of high thermal conductivity occurs at a higher rate than across materials of low thermal conductivity.
Calculate the Thermal Conductivity by the given details.
