Flow Rate

menu
Nozzle flow rate varies with spraying pressure. In general, the relationship between flow rate and pressure is:

Coverage

menu
Calculated spray angles indicate approximate spray coverages based on water. In actual spraying, the effective spray angle varies with spray distance. If the spray coverage requirement is critical, contact us for specific spray coverage data.

  How to choose turnovers, eductors
ClearNext
back

Eductor

menu
Tank Turnovers:

-For light/mild agitation use 5-15 turnovers
-For average agitation use 15-25 turnovers
-For heavy agitation of solutions with high particulates or viscous solutions use 30-50



To estimate how many eductors are needed:

-Eductors are usually placed 1 ft spaced apart 1 ft from the bottom and pointed in the desired flow direction.
