def Gharagheizi_liquid(T, M, Tb, Pc, omega):
    r'''Estimates the thermal conductivity of a liquid as a function of
    temperature using the CSP method of Gharagheizi [1]_. A  convoluted
    method claiming high-accuracy and using only statistically significant
    variable following analalysis.

    Requires temperature, molecular weight, boiling temperature and critical
    pressure and acentric factor.

    .. math::
        &k = 10^{-4}\left[10\omega + 2P_c-2T+4+1.908(T_b+\frac{1.009B^2}{MW^2})
        +\frac{3.9287MW^4}{B^4}+\frac{A}{B^8}\right]

        &A = 3.8588MW^8(1.0045B+6.5152MW-8.9756)

        &B = 16.0407MW+2T_b-27.9074

    Parameters
    ----------
    T : float
        Temperature of the fluid [K]
    M : float
        Molecular weight of the fluid [g/mol]
    Tb : float
        Boiling temperature of the fluid [K]
    Pc : float
        Critical pressure of the fluid [Pa]
    omega : float
        Acentric factor of the fluid [-]

    Returns
    -------
    kl : float
        Estimated liquid thermal conductivity [W/m/k]

    Notes
    -----
    Pressure is internally converted into bar, as used in the original equation.

    This equation was derived with 19000 points representing 1640 unique compounds.
