The following table represents the maximum flow rate in gallons per
minute (GPM) by hose ID for pressure lines and suction lines. The
recommended maximum fluid velocity for pressure systems is 15 feet per
second (FPS).

Use the following formulas for Velocity, Gallons per Minute, or Hose ID
V= Velocity in Feet per Second (FPS) = (.408 x GPM)/D2
GPM = Flow rate in Gallons per Minute (GPM) = V x D2/ .408
D = Hose ID (inches) =
The recommended maximum velocity for hydraulic systems is 15 FPS.
For higher velocity, contact Continental ContiTech Technical Support with
specific system information.
Imperial Gallon = U.S. Gallon x 0.83267
U.S. Gallon = Imperial Gallon x 1.20095
Liter = U.S. Gallon x 3.785
U.S. Gallon = Liter x .2642
