## Hydraulics and Waterworks Calc Description
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
