Hydraulics and Waterworks Calc Downloads & RevenueHydraulics and Waterworks Calc · App Store

The Hydraulics Calculator offers 94 calculators
to simplify your hydraulics, waterworks, and
civil engineering calculations — available in
both Metric (SI) and Imperial (USCS) units.

Key Features:

Smart auto-fill pickers for pipe materials,
fluid properties, channel linings, soil types,
pipe fittings, orifice/weir coefficients and
runoff coefficients
Flow regime indicators — Froude number
(Subcritical/Critical/Supercritical) and
Reynolds number (Laminar/Transitional/Turbulent)
Hydraulic jump classification
Built-in reference tables for all material
and fluid properties
