Solid Bore Nozzle Flow ChartThe chart below lists the common solid bore nozzles used in testing fire pumps and their flow rating at set pressures. All nozzle pressures are pitot gauge readings, not pump pressure gauge readings. Flows are in U.S. gallons per minute. We have only shown the most popular tips sizes. If the tip size you need is not in this chart, give us a call and we can look up the information you need. Or, if you skip to the bottom of this page, there is a formula you can use to find the answer you need.
Solid Bore Discharge FormulaD=Bore Diameter in Inches GPM=29.71D2*sqrt(NP) To calculate the theoretical reaction force use this formula: As we said, if you don't want to go through the hassle of calculating the flow, just give us a call and we will be more than happy to help. We have it in spreadsheet form so it is easy to do. |
