 def relative_humidity_wet_psychrometric(dry_bulb_temperature, web_bulb_temperature, pressure, **kwargs):
 r"""Calculate the relative humidity with wet bulb and dry bulb temperatures. This uses a psychrometric relationship as outlined in [WMO8-2014]_, with coefficients from [Fan1987]_. Parameters dry_bulb_temperature: `pint.Quantity` Dry bulb temperature web_bulb_temperature: `pint.Quantity` Wet bulb temperature pressure: `pint.Quantity` Total atmospheric pressure Returns ------- `pint.Quantity` Relative humidity Notes ----- .. math:: RH = \frac{e}{e_s} * :math:`RH` is relative humidity as a unitless ratio * :math:`e` is vapor pressure from the wet psychrometric calculation * :math:`e_s` is the saturation vapor pressure See Also -------- psychrometric_vapor_pressure_wet, saturation_vapor_pressure """
