The Pipe Flow Expert program will allow you to draw a complex pipeline system and analyze the features of the system when flow is occurring. Pipe Flow Expert calculates the balanced steady flow and pressure conditions of the system. The reported results include the flow rates for each pipe, the fluid velocities for each pipe, Reynolds numbers, friction factors, friction pressure loss for each pipe, fittings, pressures losses, pressure at join points (nodes), head pressure (grade line), pump operating points and more.


The pipeline system is modeled by drawing the join points and the connecting pipes on a drawing pane. Horizontal, vertical or sloping lines can be used to connect one node to another node. 


The physical data about the system is then entered, and typically this includes:


  • The internal size, internal roughness and length of each connecting pipe.
  • The elevation of each node (join point).
  • The In-flow and the Out-flow at each node (if applicable).
  • The elevation, liquid level and surface pressure data for each tank.
  • The performance data for each pump.
