Introduction 13

Pipe Flow ExpertSoftware Overview

Pipeline systemsrange fromverysimple oneswith a single pipe to verylarge and complexnetworkswith hundredsof interconnecting pipes. Theymaybe assimple asa single pipe carrying waterfromone reservoirto anotherreservoir, ortheymaybe more complexwith manypipelinesinterconnectingto distribute fluid overa large area, ortheycould fallsomewhere in-between such asa systemthattransfersa chemicalfroma supplycontainerto variousprocesspoints.

The pipelinesmayvaryin size and nature and willusuallyinvolve changesin elevation fromonepoint to another. These pipeline systemsmayinclude reservoirs, pressurized tanks, pumps, valves,flowcontroldevices, heat exchangersand othercomponentsthat affect flowin the pipelines.

The pipeline systemismodeled bydrawing the join pointsand the connecting pipeson a drawingpane. Horizontal, verticalorsloping linescan be used to connect one node to anothernode.The physicaldata describing the systemisentered bythe userand typicallyincludes:

The internalsize, internalroughnessand length of each connecting pipe

The elevation of each join point (node)

The In-flowand the Out-flowat each join point (if applicable)

The elevation, liquid leveland surface pressure data foreach tankThe performance data foreach pump

Data input boxesare located at the left hand side of the drawing pane. These input boxeswilldisplaythe data forthe currentlyselected node orpipe and maybe used to amend the current data. Thedata fora node, pipe, pump, etc. can be amended at anypoint during the design process.

Once the design hasbeen completed, the systemcan be analyzed and the flowand pressure resultscan be calculated. Forliquid systems, the pressure losseswithin the systemare calculated usingfriction factorsobtained fromthe Colebrook-White equation, and the pressure lossdue to friction ineach pipe isobtained fromthe Darcy-Weisbach equation. Forgassystems, the pressure lossesarecalculated using a compressible isothermalflowequationssuch asthe GeneralFlowEquation.

An initialapproximate solution isobtained using LinearTheorymethodsand an iterative approachthat adjuststhe flowratesuntilan approximate pressure balance isachieved. The solution isthenconverged to an accurate solution using sophisticated matrixtechniquesand otheriterativealgorithms.

Pipe FlowExpert definesthe elementsof the pipeline systemin a seriesof mathematicalequations.Pipe systemscan produce a highlynon-linearset of equationsthat are difficult to solve. The PipeFlowExpert software usesthe Newton method and otherproprietaryalgorithmsto solve theequations, to determine the flowrate and pressure lossin each pipe that providesa balancedsolution.

The resultsof the flowratesforeach pipe, the fluid velocitiesforeach pipe, Reynoldsnumbers,friction factors, friction pressure lossesforeach pipe, fittingspressure losses, pressure at join points

(nodes), HGLs(hydraulicgrade line), pump operating pointsand more can be viewed on the resultsdrawing and on the resultsgrid.
