The nominal IPS pipe diameters listed in this chart assume a total equivalent pipe length as listed
for friction loss calculations. A recommended internal pipe water velocity of up to 1.5 feet per second
and/or a draw down of 1 inch or less is used to develop this conservative intake sizing table. Consult
a Rain Bird engineer for values ranging outside of this chart.
