About this app

Hydrant flow test calculator: enter static and residual pressures obtained from the flow test.
2 pitot inputs: enter two pitot pressures, and the app sums both flows for the total GPM observed during the flow test.
Outlet settings: outlet diameter input with hydrant coefficient (and optional pumper outlet coefficient)
Flow extrapolation: view a Supply vs Demand curve (Flow vs PSI)
Two demand points: plot up to two demands and see PASS/FAIL results
Save test info: save results with date/time
Location logging: save test hydrant location and flow hydrant location (GPS)
History: review saved tests and results anytime

Notes

* Location is used only to record hydrant coordinates when you choose to save them.
* Designed with a clean, lightweight interface for quick field entry.
