Pipe Flow Lab

One steady incompressible run of pipe in series. The flow rate is authoritative: each segment derives its own speed, Reynolds number, regime, Darcy friction factor and losses, and those losses are what the energy equation carries along the path.

The stream

One steady incompressible stream carries the same Q through every segment. Q = 0 is a valid state.

Gauge pressure is measured relative to the ambient pressure, so 0 kPa means ambient. It may legitimately be negative. No atmospheric pressure is added anywhere in this calculation.
