## Description

Professional hydraulic engineering tool for calculating pressure losses in piping systems. Essential for engineers, plumbers, and contractors designing water distribution networks.<br>Key Features:<br><br>Calculate friction head losses using industry-standard Hazen-Williams equation<br>Support for both US (ft, gpm, psi) and SI (m, lps, bar) units<br>Pipe material library with pre-defined roughness coefficients (C-factors)<br><br>Fittings and valves database including elbows, tees, valves, contractions, and expansions<br><br>Inverse calculations to determine pipe diameter, flow rate, or length for target head loss<br><br>Real-time results showing velocity, friction loss, minor losses, and total system head loss<br><br>What Sets Pro Apart:<br>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.<br><br>Perfect For:<br><br>Water supply system design<br>Irrigation network planning<br>HVAC piping calculations<br>Fire protection systems<br>Industrial fluid transport<br>Educational purposes in hydraulic engineering<br><br>Technical Capabilities:<br>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.<br><br>Inverse Calculation Mode:<br>Unique feature allowing backward calculations - determine required pipe size for allowable head loss, maximum flow capacity, or optimal pipe length for your system constraints.<br>Simple, intuitive interface with instant results. No internet connection required.<br><br>4 Premium Modules - System Curve, Pipe Database, Pump Power Calculator, and Industrial Pack (Darcy-Weisbach for any fluid).
