def dP_demister_dry_Setekleiv_Svendsen_lit(S, voidage, vs, rho, mu, L=1):
    """Calculates dry pressure drop across a demister, using the
    correlation in [1]_. This model is for dry demisters with no holdup only.
    Developed with literature data included as well as their own experimental
    data.

    .. math::
        \\frac{\\Delta P \\epsilon^2}{\\rho_f v^2} = 7.3 - \\frac{320}
        {69.6SL - (SL)^2 - 779} - \\frac{52.4}{161 - 4.85SL} + 27.2\\left(
        \\frac{\\mu_f \\epsilon S^2 L}{\\rho_f v}\\right)^{0.75}

    Parameters
    ----------
    S : float
        Specific area of the demister, normally ~250-1000 [m^2/m^3]
    voidage : float
        Voidage of bed of the demister material, normally ~0.98 []
    vs : float
        Superficial velocity of fluid, Q/A [m/s]
    rho : float
        Density of fluid [kg/m^3]
    mu : float
        Viscosity of fluid [Pa*s]
    L : float, optional
        Length of the demister [m]

    Returns
    -------
    dP : float
        Pressure drop across a dry demister [Pa]

    Notes
    -----
    Useful at startup and in modeling. Dry pressure drop is normally negligible
    compared to wet pressure drop. Coefficients obtained by evolutionary
    programming and may not fit data outside of the limits of the variables.

    Examples
    --------
