Function metfor::dew_point_from_vapor_pressure_water

pub fn dew_point_from_vapor_pressure_water<P>(vp: P) -> Option<Celsius> where
    P: Pressure,
    HectoPascal: From<P>, 

Get the dew point given the vapor pressure of water over liquid water. This function is the inverse of vapor_pressure_liquid_water.

Returns: The dew point.
