Power Number (Np) examples for impellers

For improved cultivation its better to know your Power Number

Power Number is a dimensionless parameter used for estimating the power consumed by the agitating turbine and lost in the media. The lower the Power Number the better ability to disperse gas into the media without flooding or hurting the mammalian cell line!

Marine impeller design with typical Power Number (Np) ranging 0.2 - 2.0 in a radial flow distribution setup operating directly in the media without circular stator.

Kidney impeller design with typical Power Number (Np) ranging 0.2 - 2.0 in a radial flow distribution setup operating directly in the media without circular stator.

Pitch blade impeller design with typical Power Number (Np) ranging 0.2 - 2.0 in a radial flow distribution setup operating directly in the media without circular stator.
