    You can compute it using Fourier's law. It states that the rate of heat transfer through conduction is directly proportional to the thermal gradient (dT/dx). Mathematically,

    q_x = - k * A * dT / dx (1D conduction)

    where,

    q_x - rate of heat transfer in x direction

    k - thermal conductivity of the material

    A - area normal to the direction of heat transfer

    dT / dx - thermal gradient

    The minus sign is necessary because heat is transferred in the direction of decreasing temperature.

  • Thanks @pankajhr , So what is the physical meaning of the thermal conductivity in the Fourier's conduction equation?

    Thermal conductivity is a transport property which indicates the rate at which energy is transferred through conduction. Efficient conductors have a high thermal conductivity. Materials with poor thermal conductivity are referred to as insulators.
