## What is Pipe Flow Liquid Pipe Diameter?

Pipe Flow Liquid Pipe Diameter is a pipe sizing calculator app from Pipe Flow Software that calculates the minimum internal pipe diameter needed for a given flow rate at a specified maximum pressure loss.

Pipe Flow Software applications are used by engineers in over 100 countries worldwide.

The Pipe Diameter 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 Diameter 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 their pipe sizing 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 Diameter software has unrivalled functions and features:
 
- Liquid properties database for water, oils, acids, and other fluids.
