Thermal Conductivity Calculator

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.

Thermal Conductivity Calculation

    Heat Transfer Rate or Flux :
    qx =KTM*ΔT/x

    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.
    Calculate = Heat Transfer Rate or Flux
    Thermal Conductivity Constant (KT) = 25 calorie/degree-cm-s
    Temperature Differential (ΔT) = 15
    Distance or Length(x) = 10 cm

    Apply Formula:
    qx =KT*ΔT/x
    Heat Transfer Rate or Flux (qx) = 37.5 calorie/cm2-s
