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, 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 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
