If Upstream ID is left blank, the line follows the line above it as a series pipeline. Enter the ID of an upstream line to branch from it. The default is a series pipeline; a tree is formed only where a branch is entered.
Branched networks only, no loops
Every line has exactly one upstream line (a tree). This tool does not solve looped networks, which require iterative methods (EPANET or similar). Because the network has no loops, the solution is direct and exact.
No active pressure controls
You can add a fixed minor-loss valve (a k-value), but not pressure-reducing or pressure-sustaining valves (PRV/PSV). Their open/closed state depends on flow and pressure, which would force iteration.
