## Formula

**Heat Transfer Rate or Flux :**

q_{x} =K_{TM}*ΔT/x

**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.

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.

**Example:**

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

**Solution:**

**Apply Formula:**

q_{x} =K_{T}*ΔT/x

**Heat Transfer Rate or Flux (q _{x}) =**

**37.5 calorie/cm2-s**
