Full description
The COMPLETE version of HydroCalc, with what the free app doesn't have: the FITTINGS SELECTOR. Pick elbows, valves, tees and reducers piece by piece and the app computes minor losses for you — in the calculator, the inverse calculator and the system curve. No K-value tables, no transcription errors. ALL INCLUDED: pump power, system curve, pipe database and Darcy-Weisbach with real fluids come with the app. One purchase, no in-app purchases. 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 Plus 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. ――――――――――――――――――――― WHICH ONE IS FOR ME? ► HydroCalc Plus (this app) The complete version for daily professional work, with the fittings selector. ► HydroCalc (free app, separate) To get started: head loss with a manual K value, and advanced modules as an optional purchase inside that app. Note: they are independent apps — buying one does not unlock the other. ―――――――――――――――――――――
