Version 7 Features
Here is a list of features and changes from PIPE-FLO version 6 to PIPE-FLO version 7.
Nodes are connection points between pipelines. These can be simply points where you specify an elevation, or they can be a pump, component, control, tank, or demand.
Pumps, components, and controls are no longer installed in pipelines. These objects are now placed on nodes or you can place them anywhere in your system, even before you design your pipelines.
The PIPE-FLO project is now completely integrated into one project file - there are no longer separate linelist and lineup files.
The default pipe and fluid information is now split up into Fluid Zones and Specifications.
Valve and fitting installation has been streamlined. Many items, such as a Tee fitting, require only a click of the mouse to install.
A new native flow rate of barrels per hour (bph) has been added.
Four new pressure units have been added: in H2O, mm H2O, in Hg, and mm Hg.
Both pipeline and node names can be automatically generated, with the ability to use user specified prefixes.
A constant density is no longer used for systems that use volumetric flow rates.
NOTE: If a node's connecting pipelines have different fluid densities, the volumetric flows will not sum to zero at the node (the flows into the node will not equal the flows out of the node). However, this does not mean that the node is not balanced. Recall that Kirchoff's first law states that the algebraic sum of the mass flow into and out of all nodes must equal zero. If you were to convert the volumetric flows to mass flows using each pipeline's fluid density, the flow rates would sum to zero.
Demands are enhanced - there is now a flow demand, where you specify a flow leaving or entering a system, or a pressure demand where you specify a known pressure in the system.
FCVs, PRVs, and BPVs and now be set to a fully open (non-controlling) position.
There are now seven list windows where you can view design data and results: Pipelines, Nodes, Controls, Tanks, Demands, Pumps, and Components.
The Check Valve control is no longer supported. If you want the program to check the flow during the system calculation, you can select the pipeline and choose the Prevent Backflow menu item.
The Pump Control is no longer supported, its operation is replaced by the ability to specify pump operation (curve or fixed flow) by lineup.
All items in the system (pipelines, nodes, fluid zones, specifications, pumps, components, controls, etc.) can be renamed directly in their dialog box.
Copying on the FLO-Sheet has been enhanced - you can now copy sections of pipes to themselves; items such as tanks, demands, pumps, controls, and components can be copied as well.
Dialog box data entry has been streamlined with property sheets so that you can enter or modify multiple items from one dialog box.
Symbol selection has been streamlined - you can now view the symbols in a list at one time.
Customize the FLO-Sheet to show the results you want to see - for example, flow or velocity; dP or HL, pressure or hydraulic grade.
The tagging feature has been enhanced so that you now use it to select the items you want to print design data for.
Save design data to a text file as well as calculated results.
Notes can be attached to pipes, nodes, tanks, demands, pumps, components, controls, lineups, and system file; notes can be printed with your other reports are separately.
