The HE-3 or HE3 is a patented impeller by Chemineer. It has 3 blades and is called by Chemineer a high-efficiency impeller. It is considered an axial flow impeller, because under turbulent conditions the discharge of the fluid is parallel to the shaft (0 degrees).

Turbulent Power Number Np=0.22 and Flow Number Nq=0.47 for D/T=0.4

There is much more data on several impeller types in this article, and this page will be updated.

Reference: The data above was extrapolated from graphs in the reference and is valid for D/T=0.4. The reference includes data for D/T=0.2, 0.3, 0.4, and 0.5, with OB/T=1/3.
