HydroCalc Plus

Transparent Blue Water

About this app

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.
