This compact bench-top apparatus uses smooth, industry standard plastic pipe, commonly used in domestic and other small-bore water systems.

It works with TecQuipment’s Digital Hydraulic Bench (H1F). Either bench supports the apparatus and circulates and measures the water flowing through it. This apparatus has a single circuit with bends, pressure tappings and an expansion-contraction. A ball valve at the pipe exit controls water flow.
Each pressure tapping point in the pipe connects to a piezometer tube in the vertical panel of the apparatus. During experiments, these tubes measure and compare pressure differences across the bends, expansion and contraction.

A useful diagram on the apparatus shows the main dimensions of the pipework and fittings. It also shows the positions of the tappings and the tubes that they connect to. The product includes a hand-pump to adjust the datum of the piezometer tubes.

This apparatus is a smaller version of TecQuipment’s Losses in Piping Systems (H16), which has two pipe circuits and scope for further project work.

Measurement and comparison of losses in:

  • Mitre bend
  • Elbow bend
  • Large radius bend
  • Sudden expansion
  • Sudden contraction
Case Study
UK National College of Nuclear North Hub

When it came to finding teaching equipment to support a new technical college for nuclear in the Lake District, UK, TecQuipment was called upon.

H1F - Base Unit

Provides a controlled recirculating water supply and accurate flowmeter for hydraulic and fluid mechanics experiments.

H16 - Experiment

An apparatus to allow students to investigate the friction losses in piping systems. The large open format of the apparatus makes it ideal for students working in small or large groups.

H408 - Experiment

A floor standing apparatus to allow students to investigate the phenomena of laminar, transitional and turbulent flows in pipe systems.

H7 - Experiment

A bench-mounting apparatus to allow students to investigate friction losses in a small-bore horizontal pipe under laminar and turbulent flow conditions.
