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.
