Venturi Eductor Mixer

Technical Design notes:
Eductor section is designed as a venturi nozzle per ISO 5167-1 (1991) pp. 28 & 37
Outlet diverging section has included angle of 8 degrees (typical of traditional venturi tube)
Inlet nozzle has inlet included angle of 21 degrees (typical of traditional venturi tube)
Annulus for outside flow, spacing between inlet nozzle and eductor section, has hydraulic diameter equal to inside diameter of inlet pipe.

Should produce 3 to 5 times more flow than a normal return pipe.

Once assembled nozzle secured to return pipe that has been wrapped with some teflon tape to make a secure fit.
