That depends on what you're trying to do with the air Shambav. If you 
are meeting outdoor air requirements to maintain Indoor air quality then 
refer to ASHRAE 62.1. If you are attempting to condition the space (heat 
or cool) with the air then volume flow

     V = Q / rho.Cp.deltaT

where Q = Heating / Cooling rate, Rho = density of air, Cp = specific 
heat, DeltaT = difference in room air temperature and off coil.

A VAV system does both of these (supplies outdoor air and room 
conditioning) and uses a mixing box.

If you want to understand VAV get hold of LearnHVAC
