Calculate air exchange (cfm) | greenheck. It is generally a good approximation to use the «2nd fan law» equation you mentioned.

Apply It In The Field:

Static pressure creates resistance against air movement in the ducts of an hvac system, and air handling units must. Ducted 0.20 to 0.40 per 100 feet of duct (assuming duct air velocity falls within 1,000 to 1,800 feet per minute) fittings 0.08 per fitting. At 1000 cfm, you read a 0.9″w.c.

Cfm = (1,000 Sq Ft * 8 Ft * 4) / 60 Min = 533 Ft3/Min = 533 Cfm.

You use a variation of the fan laws to calculate the system constant. This turbo size calculator gives the numbers you need to analyse turbo compressor maps so you can find a good turbo for your engine. Max friction rate (in w.c./100 ft):
