Read full description

Size a pipe from the numbers you already have. Pipe Diameter Calculator finds the internal diameter of a circular pipe from your flow rate and target flow velocity, or checks the velocity in a pipe whose internal diameter you already know. Built for quick line sizing on site, at the desk or in class, it suits piping, mechanical and process engineers, plumbing and HVAC professionals, pipefitters and engineering students. TWO WAYS TO CALCULATE • Find the internal diameter: enter the flow rate, fluid density and target velocity • Check flow velocity: enter a known internal diameter and the flow rate VOLUME OR MASS FLOW • Start from a volume flow rate or a mass (weight) flow rate • Choose your inputs and the value to solve for on the Selection screen CLEAR RESULTS • Cross-sectional area of the pipe • Weight (mass) flow rate • Flow velocity • Internal pipe diameter METRIC AND IMPERIAL UNITS • Pick a unit for each input and each result from its own menu • Mix units freely, for example enter the diameter in centimeters and read the velocity in feet per second SIMPLE AND PRIVATE • One clean screen, a Calculate button and a one-tap clear button • Free to download • No data collected HOW IT HELPS DAY TO DAY • Pick a starting pipe size for a new line before you check it against your design standard • Check whether the velocity in an existing pipe is reasonable for the duty • Work through flow and velocity exercises for coursework and exams Results are a quick engineering estimate based on the values you enter. Always confirm final pipe sizes against the codes, standards and design criteria that apply to your project. Download Pipe Diameter Calculator and size your next line in seconds.

About

FlowAnalyzer

Features
Read full description

FlowAnalyzer brings professional hydraulic analysis to your mobile device. Analyze and visualize water distribution networks with simulation powered by the industry-standard EPANET 2.3.5 engine. Results are shown in the units declared in your .inp file. PROFESSIONAL ANALYSIS Run comprehensive hydraulic simulations to analyze pressure, head, flow, and velocity throughout your network. Color-coded results show where pressure is low or velocity is high against fixed reference bands. They are a visual aid, not design criteria: verify against the locally applicable standard. VISUALIZATION View your network with color-coded nodes and pipes that show hydraulic conditions. A legend shows the pressure and velocity color bands in your network's units and marks nodes with no flow path. Zoom up to 2000x to inspect individual components in detail. KEY FEATURES • Import and analyze EPANET .inp files • Run steady-state and extended period simulations • Interactive network visualization with color coding • View pressure, head, demand, flow, and velocity results • Detailed node and pipe properties • Component counts by type (junctions, tanks, reservoirs, pipes, pumps, valves) • Engine warnings shown after each run • Sample networks included for learning • Optional Google Maps background under your network (uses Google Maps and needs a connection) • Field notes that can save your GPS position (kept on your device) FREE VERSION: • Networks of any size • Run hydraulic simulations • View pressure maps over time • Create and edit patterns FLOWANALYZER PRO (one-time in-app purchase): • Export results to PDF reports • Export data to CSV • Export your network as an .inp file • Save your network's alignment on the map One-time purchase. No subscription. DESIGNED FOR PROFESSIONALS Built for water engineers, hydraulic consultants, urban planners, and water utility professionals. From a small neighborhood network to a city-wide system, FlowAnalyzer sets no limit on network size; simulation time on very large models depends on your device. FIELD-READY Analyze networks on-site, in the field, or in the office. The network, the calculation and your files work without internet. The optional map background needs a connection. Open .inp files from your device storage, cloud drives available in the system file picker, or email attachments. TECHNICAL CAPABILITIES • Supports junctions, tanks, and reservoirs • Handles pipes, pumps, and valves • Warnings when a run is halted as hydraulically unbalanced • Extended period simulation (EPS) • Time-based analysis with interactive timeline EDUCATIONAL TOOL Useful for students and professors teaching hydraulic engineering, water resources, or civil engineering courses. Use included sample networks to learn hydraulic principles and network behavior. ABOUT THE ENGINE Uses EPANET 2.3.5, the open-source release of the hydraulic modeling engine originally developed by the U.S. Environmental Protection Agency (EPA). FlowAnalyzer is an independent application developed by Transparent Blue Water LLC and is not affiliated with, endorsed by, or sponsored by the EPA. EPANET is a trademark of the EPA. Results depend on your model and its data. Verify them independently before using them for design or operation decisions. FlowAnalyzer does not certify compliance with any design standard. GET STARTED Import your existing .inp files. Run a simulation with a single tap and see the results on your network. Download FlowAnalyzer today and bring professional hydraulic analysis to your mobile device.
