def Nu_cylinder_McAdams(Re, Pr):
    """Calculates Nusselt number for crossflow across a single tube
    at a specified `Re` and `Pr`, both evaluated at the film temperature. No
    other wall correction is necessary for this formulation. Also shown in
    [2]_.

    .. math::
        Nu = (0.35 + 0.56 Re^{0.52})Pr^{0.3}

    Parameters
    ----------
    Re : float
        Reynolds number with respect to cylinder diameter, [-]
    Pr : float
        Prandtl number at film temperature, [-]

    Returns
    -------
    Nu : float
        Nusselt number with respect to cylinder diameter, [-]

    Notes
    -----
    Developed with very limited test results for water only.

    This method applies to both the laminar and turbulent regimes.

    Examples
    --------
