Pipe Flow Wizard is a fluid flow rate and pressure loss calculator app from Pipe Flow Software. Perform flow rate calculations, calculate pressure drop in a pipe, size a pipe diameter, or calculate a maximum pipe length for a given flow rate at an allowed pressure loss. The original Pipe Flow Wizard software is used by engineers in over 100 countries worldwide and now the new mobile version for iOS brings the same calculations to iPhone and iPad. Find friction loss, find flow rate, find minimum size of pipe diameter for given flow rate and pressure loss, or find length of pipe for a specified maximum pressure loss. Pipe Flow Wizard works for liquid and gas flow and allows for the inclusion of valves, fittings, and changes in elevation. Pressure losses for non-compressible fluids (liquids) are calculated using the Darcy-Weisbach formula, and for compressible fluids (gases), the user can choose from the General Fundamental Flow, Complete Isothermal Flow, AGA, IGT, Panhandle A, Panhandle B, or the Weymouth equation. Pipe Flow Wizard has databases for pipe materials, pipe diameters, pipe fittings (k factors), and fluids. Users can also specify and add their own data for pipe materials, sizes, fittings and fluids. Data and results can be entered and displayed in either imperial or metric units and the units of each individual field can be specified separately. Calculation results include Reynolds number, friction factor, flow type (laminar or turbulent), friction losses, fitting losses, fluid velocities and more. Pipe Flow Wizard calculation results have been verified against 50 cases of published results from well known sources. These include calculated results for both liquid and gas systems. The results of these calculations are included in two Results Verification PDF documents which can be accessed from within the App. There is also a compressible gas flow equations document and a comprehensive user guide. The Pipe Flow Wizard App makes it easy for pipe system engineers to perform flow rate and pressure drop calculations, where the calculation results can easily be shared as an Excel or PDF Report. Calculations can also be saved to the iPhone or iPad and data files can be shared with other users of the software on either macOS or Windows. The Pipe Flow Wizard software has unrivalled functions and features that aren't often found in other flow rate and pressure loss calculator apps: - Liquid properties database for water, oils, acids, and other fluids. - Gas properties database for air, nitrogen, natural gas, and other compressible fluids. - Pipe material database for various Steel, Aluminium, Copper, HDPE, and other pipes. - Fitting database for standard valves and bends, with associated K factor values. - User definable custom materials, fluids and fittings. - Gas properties calculator to help with the creation of user defined gas data at a specific temperature and pressure condition. - Professional Excel and PDF reports showing calculation results. - Results verification against published data to provide confidence in the calculation results. - Configurable post decimals for display on screen and in reports. - Automatic conversion between a wide range of units. - Compatibility with Pipe Flow Wizard files for macOS and Windows. - High quality, reliable software, and unrivalled customer support. Pipe Flow Software programs are trusted and used by engineers in over 100 countries worldwide. Pipe Flow Wizard offers auto-renewable subscriptions. Purchasing a subscription will remove all calculation restrictions and enable full use of the Pipe Flow Wizard App. When a subscription expires, the App will return to Trial Mode, where certain calculations are restricted.

Read full description

With version 10, the application allows you to quickly visualize relational values related to pipes and elbows (Carbon Steel / Stainless Steel) according to ISO / ASME standards, making it a practical tool for industrial piping. An ultra-fast and intuitive way to retrieve: Diameter → Angle → Radius → Extrados → Intrados, regardless of the angle or diameter, in a single step. This provides up to 810 possible entries with one click. With this version, you can choose how to control diameter selection: via a slider, or via pre-filled input fields. ElbowData is free forever. Features Elbow formats: 2D / 3D / 5D Segmented elbows (lobster back): 8 generators / 12 generators / 16 generators PDF abacuses and isometric sheets including: bill of materials based on the selected language, technical memo, generator templates Inch / millimeter conversion Scientific calculator optimized for industrial piping Saved language selection This version benefits from UI, design, and ergonomic optimizations. Advertisements are now non-intrusive, ensuring a smooth and free user experience, with rewarded ads and technical articles related to industrial piping. You can support the developer with your suggestions and/or access the premium version. Thank you! If you have any feedback about the application, feel free to contact me by email.

Verdict

The call

The clearest difference is rating: Pipe Flow Wizard at 4.5 against ElbowData's 3.0. Pipe Flow Wizard also leads on ads (none vs shown) and ratings volume (102 vs 2). ElbowData's advantage is review sentiment (75% vs 50%) and monetization model (ad-supported vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Pipe Flow Wizard sells 3 in-app purchases, starting at $9.99 per month and ElbowData sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Pipe Flow Wizard holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Pipe Flow Wizard has 102 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Pipe Flow Wizard's written reviews are positive against 75% of ElbowData's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 12, 2026 and September 22, 2026 respectively.
