Pipe Flow Expert version 8.17 - released August 2023.
Pipe Flow Expert version 8.16 - released April 2023.

Version 8 is a major release update with significant program enhancements.

The following features and updates are available in version 8:

New Orifice Component:
  • Orifice Component Calculations:
    Sharp Edged Orifice
    Round Edged Orifice
    Bevel Edged Orifice
    Thick Edged Orifice
    Calculates pressure loss through orifices for liquid systems.
    Calculates pressure loss through orifices for gas systems.
    Automatically takes account of the gas density at the entry of the orifice.
    Calculates for orifices in straight pipes.
    Calculates for orifices in transition sections
    (where the upstream and downstream pipes are of different size diameters)
Orifice Auto Sizing:
  • Orifice Component Sizing:
    Auto size orifice diameter to achieve a specified flow rate.
    Size orifice diameter to produce a given pressure drop
    (for a required flow rate, at a specific Orifice inlet pressure)
    Orifice component sizing works for both liquids and gases.
Calculation Engine Enhancements:
  • Improved Calculation Engine Algorithm:
    Significant improvement in handling complex edge cases in large pipe networks.
    Improved identification and selection of critical pipe loops when generating equations.
    Enhanced convergence algorithms.
Decimal Places:
  • Decimal Places Configuration and Overrides:
    By default, numbers are displayed to an appropriate number of decimal places
    (based on the given value and unit, and this generally works well in most cases)
    New functionality allows the user to override and specify the number of decimal places
    for each unit (diameter, length, pressure loss, etc) when values are displayed
    - On System Drawing
    - On Results Sheet
    - On PDF Report
Config Options:
  • Config Options Defaults:
    Config options can be saved as default values that are automatically loaded on start-up.
    New 'Editor' tab allows configuration of grid type and other drawing options.
Larger Drawing Area:

    Nodes within the selection that overlap existing nodes within the main system are automatically removed.
    Pipes within the selection are joined onto the existing nodes
    (effectively 'attaching' the selection onto part of the existing model).
Move Tool allows Connection to Existing Drawing:
  • Move Tool Enhancement:
    Moving a node to stretch, shorten, or reposition an existing pipe that is connected to it, now allows the selected node to be placed over a different node within the existing system, to join the pipe on to this part of the model. The selected node is automatically removed and end of the pipe is connected on to the other existing node.

  • New context sensitive popup submenu
    Allows individual items on the current pipe to be copied to their own clipboard.
    An individual fitting, component, control valve, or pump can be pasted onto a different pipe.

  • Easier Pan of drawing is now supported while using standard 'Show' tool.
  • Pipe Flow Expert Quick Start Guide PDF is available from the help menu.
  • Pipe Flow Expert Results Verification PDF is available from the help menu.
  • Improved solution convergence for larger systems.
Pipe Flow Expert 2008 v2.05 released 9th January 2008 included:
  • Network Licensing is now available.
  • Installation to a Shared Drive is now supported. The software can now be installed to any hard drive including local drives, network drives or USB memory sticks.
  • Cut, Copy and Paste of multiple items is now supported. Multiple items can now be selected, updated, moved and copied. Items can even be copied between different drawings.
  • Multiple item updates are also supported.
  • Pipes and Nodes can now be amended as a group update with one operation to allow easy configuration of pipe diameters and node elevations (and many other attributes).
  • Coloring of pipes in design mode is now supported. Pipes can be drawn in different colors and line styles to aid in the visualisation of items within the system.
  • Results Screen now shows items according to a Color Gradient. A results item such as flow rate or pressure loss can be selected and automatically mapped on to a color gradient which is then used to determine the color of the item on the results screen. This feature makes it easy to visually see what is happening in your system, i.e. where the highest flows are, or where the highest pressure loss is.
  • Fixed Head Pumps are now supported. The pump head to be added can now be specified directly, which makes it easy to find out if a particular pump head is enough to solve your system and meet all of the design requirements.
  • Zoom to selected area on drawing in design mode.
  • Energy calculations are now shown on Results Sheet.

Pipe Flow Wizard
Latest Release: Version 1.12, 5th March 2010

This release provides several useability and bug fix updates which include:
  • Updated Calculation in Find Length screen
    If Imperial Units were selected and a volumetric unit was selected for liquid flow which was not present in the gas flow units and the user then switched to calculate gas flow (or the user reselected the gas flow units after switching to gases) then an incorrect flow rate was used in the calculation (compared to the data displayed on screen) which resulted in an incorrect length calculation. NOTE: This issue ONLY occured on the Find Length screen and has been fixed in this update.
  • Allow entry of numeric data without inclusion of a decimal point
