HydroCalc Plus

Professional hydraulic engineering tool for calculating pressure losses in piping systems. Essential for engineers, plumbers, and contractors designing water distribution networks.
Key Features:

Calculate friction head losses using industry-standard Hazen-Williams equation
Support for both US (ft, gpm, psi) and SI (m, lps, bar) units
Pipe material library with pre-defined roughness coefficients (C-factors)

Fittings and valves database including elbows, tees, valves, contractions, and expansions

Inverse calculations to determine pipe diameter, flow rate, or length for target head loss

Real-time results showing velocity, friction loss, minor losses, and total system head loss

What Sets Pro Apart:
Unlike basic calculators, HydroCalc Pro accounts for both major losses (pipe friction) and minor losses (fittings and valves). The app includes a database of K-factors for various components, allowing accurate total system pressure loss calculations.

Perfect For:

Water supply system design
Irrigation network planning
HVAC piping calculations
Fire protection systems
Industrial fluid transport
Educational purposes in hydraulic engineering

Technical Capabilities:
The app considers all critical factors affecting pressure loss: flow velocity, pipe diameter, internal roughness, pipe length, and fitting configurations. Materials include PVC, polyethylene, steel, cast iron, concrete, and more with accurate C-factors ranging from 120-150.

Inverse Calculation Mode:
Unique feature allowing backward calculations - determine required pipe size for allowable head loss, maximum flow capacity, or optimal pipe length for your system constraints.
Simple, intuitive interface with instant results. No internet connection required.

4 Premium Modules - System Curve, Pipe Database, Pump Power Calculator, and Industrial Pack (Darcy-Weisbach for any fluid).
