number mixing_ratio_from_vapour_pressure(p: number, e: number)
Computes the mixing ratio from the given (total) pressure and vapour pressure, where
p: pressure (Pa)e: vapour pressure (Pa)
The result is the mixing ratio in kg/kg units. On error nil is returned. The computation is based on the following formula:
