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.

Read full description

Pipe Flow Liquid Pipe Length is a calculator app from Pipe Flow Software that calculates the maximum length of pipe needed before a given pressure loss is exceeded for a specified flow rate in a known pipe diameter. Pipe Flow Software applications are used by engineers in over 100 countries worldwide. The Pipe Length App has an intuitive user interface that allows for easy entry of the input data, including changes in elevation, and selection of valves & fittings. Comprehensive results include Reynolds number, friction factor, friction losses, fitting losses, fluid velocities and more. Each result is clearly displayed using expandable sections that reveal further information as needed. Users can select pipe materials, pipe diameters, pipe fittings (k factors) and liquids from the integrated databases, and these can also be extended with user specific data for custom pipe materials, diameters, fittings, and liquids. The App can operate in Imperial or Metric units and each individual field can be further customised to use a specific unit. Results values can be displayed to a specified number of decimal places. Pipe Flow Liquid Pipe Length calculation results have been verified against multiple cases of published data from well known sources. The results of these calculations are included in the Results Verification PDF document which can be accessed from within the App. Engineers can easily perform maximum pipe length calculations in the office or on site. Professional Excel and PDF reports can easily be shared with others. Results can also be saved to the library within the App. The Pipe Flow Liquid Pipe Length software has unrivalled functions and features: - Liquid properties database for water, oils, acids, and other 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. - Professional Excel and PDF reports showing calculation results. - Results verification against published data to provide confidence in the calculation results. - Configurable post decimal places for display on screen and in reports. - Automatic conversion between a wide range of units. - Compatibility with Pipe Flow Wizard files for iOS, macOS and Windows. - Calculation results based on the same reliable calculation engine that is used by Pipe Flow Software's premier Pipe Flow Expert software, which is trusted by users in over 100 countries worldwide. - High quality, reliable software, and unrivalled customer support.
