I am trying to estimate the scfm of air needed for mild to moderate agitation in a approx. 10 m3 cylindrical tank filled with water. (approx 2 m dia)
What are good correlations? My estimate was 0.5 scfm would suffice for this tank.
The correlations I am finding seem very conflicted almost a factor of 100 off.
Perry's Handbook recommends about 0.01 cfm per ft2 of tank cross section area. Another correlation (see link below) recommends 1 cfm per ft2 of tank area.
e.g.

NOTE: For moderate to heavy air agitation in tanks up to 36" deep, 1 to 1 1/2 cfm of air is required per square foot of tank surface area
