Re: What are the power numbers for standard agitator impellers?25 August 2008 at 1:29pm
Typical turbulent power numbers for different impellers are as follows:
Pitched-blade (4 blades, 45 deg angle, W/D = 0.2) 1.37
Straight-blade (4 blades, W/D = 0.2) 3.96
Hydrofoil (typical 3 blades, narrow blades) 0.31
Saw-tooth disperser blade
(depends on number of teeth, height of teeth, pitch of teeth) 0.35 to 0.88
Anchor impellers are usually designed on the basis of a viscous power number and depend on geometry, blade width, height, and wall gap.
I wish to know different power numbers for standard agitator impellers (Pitched blade. Straight blade. Anchor. Disperser etc.)
Have an insight or suggestion?
