HydroSewer vs Pipe Flow Calculations

HydroSewer is a professional stormwater and sewer network analysis tool powered by the EPA SWMM 5 engine. Build, analyze, and simulate drainage networks from your phone or tablet. KEY FEATURES - Import standard EPA SWMM input files (.inp) and simulate them with the EPA SWMM 5 engine on your device, with no account and no cloud - Junctions, outfalls, storage, conduits, pumps, weirs, orifices, and subcatchments on an interactive canvas - Step through results over time: depth at nodes, flow and velocity in conduits, and more - Edit node, link, and subcatchment properties; renaming or deleting an element updates the data that refers to it, and broken references in older projects can be repaired - Give a node its sewage flow (DWF), with an optional hourly pattern, and a direct inflow; before a run, the app flags flat pipes, unset manholes, or no inflow at all - New network, Save, and Save as in the menu; Demo Village, a sample network, to try it all MAP BACKGROUND (OPTIONAL) - Your network over Google Maps, map or satellite, with adjustable visibility - Find your area on the map: tap your town and HydroSewer proposes the coordinate system that fits, if it knows one - Or set UTM, or a Transverse Mercator grid in Advanced - A .inp that declares a supported EPSG code (Q_VAR_PROJECTION) lands in place with no setup - Local coordinates? Line the network up by tapping a node and its place on the map, a few times - You turn the map on. It needs a connection; without one, the network is shown without it LAY OUT A NETWORK IN THE FIELD Start a new network and tap Use my location: the map centers where you are and a dot shows your position as you walk. Add each manhole by tapping its place on the map; your location never places or moves one. A preliminary layout, not a survey. FIELD NOTES - Attach notes and photos to any manhole, outfall, or pipe: as-built discrepancies, observations, a "check this" for the office - Open or resolved; elements with open notes are highlighted, and one list gathers every open note - With location allowed, a note records where it was taken and how accurately, with Show on map - Saved in your project, never in the .inp file CORE FEATURES WITHOUT INTERNET Modeling, simulation, saving, and field notes work with no connection, wherever the signal doesn't reach. Apart from the store's purchase service, only the optional map background uses the internet, through Google Maps. PRIVACY Transparent Blue Water does not receive your data. When you turn on the optional map background, Google Maps receives the map area you view. Your GPS reading, if you allow it, is used on your device and never sent anywhere; a note's position stays in your project and its PDF until you share them. FREE, WITH NO SIZE CAP No cap on network size, field notes, or photos; the map background is free too. HydroSewer Pro is an optional one-time purchase that adds: - Export the network as a standard SWMM .inp file - Export node and link results to CSV, every time step - A PDF report of your field notes with your logo, model data per element, the photos, and map links to where notes were taken - Save a network's alignment on the map IMPORTANT HydroSewer is an independent engineering tool. Results are computed by the EPA SWMM 5 engine and must be reviewed and verified by a qualified, responsible engineer before any design, construction, permitting, or other professional use. HydroSewer does not certify or guarantee compliance with any code, standard, or regulation, and is provided "AS IS" without warranty of any kind. HydroSewer is not affiliated with, endorsed by, or sponsored by the U.S. Environmental Protection Agency (EPA). References to EPA and SWMM are used solely to identify the simulation engine. Map data and imagery: Google Maps.

Pipe Flow Calculations is a professional engineering app designed for accurate and fast calculation of fluid flow in pipes. It helps engineers, technicians, and students analyze flow behavior, pressure losses, and key fluid parameters in real-world systems. Whether you are designing a pipeline, checking an existing system, or learning fluid mechanics, this app provides reliable results with an intuitive interface. Key Features - Pressure drop calculation - Pipe diameter and flow rate calculations - Flow velocity and Reynolds number - Friction factor and fluid properties - Support for multiple calculation scenarios - Metric and Imperial unit systems - Accurate engineering formulas and methods Designed for Real Engineering Use This app is not a basic calculator. It is built for real engineering workflows: - Analyze pipe systems and optimize performance - Compare different calculation scenarios - Work with realistic fluid properties - Get instant results for quick decision making Useful for Students and Professionals
