r'''Calculate the viscosity of a liquid using the 3-term Antoine form
    representation developed in [1]_. Requires input coefficients. The `A`
    coefficient is assumed to yield coefficients in centipoise, as all 
    coefficients found so far have been.

    .. math::
        \log_{10} \mu = A + B/(T + C)

    Parameters
    ----------
    T : float
        Temperature of fluid [K]

    Returns
    -------
    mu : float
        Liquid viscosity, [Pa*s]

    Notes
    -----
    No other source for these coefficients has been found.
