The mixing ratio of water vapour in air is the weight of water vapour mixed into a given weight of dry air. The unit is kg/kg. This is the vertical axis of the psychrometric chart. There are two common uses for the mixing ratio. In meteorology the mixing ratio is useful for tracing the properties of vast air masses as they rise or fall in the ...

The units of air density within the model are kg/m3, therefore if the pollutant emission units are in kg, the effect of dividing the pollutant mass by air density is the same as dividing the final air concentration kg-pol/m3 by air density kg-air/m3, resulting in a mass mixing ratio of kg-pol/kg-air. To convert the mass mixing ratio to a volume ...

There is nominal mix up to M25 (1:1:2) proportion is available in I.S code, for above mix ratio you have to do mix design with knowing all material properties. refer mix design from I.S code 10262 ...
