• Measurement of head loss versus discharge for different sizes of pipes.
  • Characteristics of flow through interconnected pipes of different sizes.
  • Characteristics of flow through parallel pipe networks.
  • Characteristics of flow through series pipe networks.
  • Application of doubling pipes on existing networks to increase flowrate.
  • Characteristics of flow around a ring main and the effect of changes in supplies and off-takes.


  • Specifically designed to allow the setting up of a wide range of different pipe arrays (networks).
  • Pipe network mounted on freestanding support frame to use with Hydraulics Bench.
  • Test pipes are all 0.7 m long with approximate inside diameters of 1x 9.5mm, 2x 14mm, 1x 12.7mm, 1x 18.5mm.
  • Differential pressure measurements obtained using a U-Tube Manometer upto 1m with 1mm graduation with self-sealing quick-release connections to the pipe network.
  • Flows into and out from the appropriate network can be varied individually.
  • Water manometer with hand pump.
  • Mercury manometer (optional)

The arrangement of PVC pipes and fittings is mounted on a freestanding support frame that is designed to stand independently and use Hydraulics Bench as water supply or tap water. Connection to the water source is made via a reinforced flexible tube quick release fitting.

Isolating valves allow a wide range of different series, parallel and mixed pipe configurations to be created without draining the system. Flow into the network and flow out from the network at each outlet can be individually varied to change the characteristics of the system. All test pipes are installed using unions with ‘O’ ring seals that allow the pipes with different diameters to be repositioned without the use of tools. Self-sealing quick release fittings at strategic points in the network allow rapid connection of the pressure manometer, allowing appropriate differential pressures to be measured. Flow leaving any of the outlets in the network is measured using the volumetric Hydraulics Bench.
