The nomogram below is provided as an aid in determining the
correct hose size.
How to use the nomogram: Determine the proper fow rate your
system requires, then connect a straight edge from the selected
fow rate to the recommended velocity range. The required hose I.D.
will appear at the intersection of the straight edge and the center
column. If the straight edge passes through the scale between sizes
listed, use the next larger I.D. hose.
Example: Locate 16 gallons per minute in the left-hand column and
20 feet per second (fps) in the right-hand column (the maximum
Flow Capacities at
Recommended Flow Velocities
recommended velocity range for pressure lines). Lay a straight
edge across these two points. The inside diameter required is
shown in the center column at or above the straight edge. In this
case, we need a hose I.D. of 0.625 (5/8”) inch (or larger).
Use the same procedure for suction of return lines, except utiliz-
ing their respective maximum recommend velocities.
