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.

H1F - Base Unit

A mobile self contained bench with recirculating water supply. It provides water at different flow rates direct to experiments and includes digital flow display for hydraulic and fluid mechanics experiments.

H16 - Experiment

Free standing mobile apparatus, demonstrates pressure losses in several small bore pipe circuit components, typical of those found in central heating systems.

H408 - Experiment

A mobile, vertical panel featuring various pipe configurations to demonstrate flow and losses in different pipes fittings and valves. Includes Pitot tube, Venturi and orifice meters for flow measurement.

H7 - Experiment

A small bore straight test pipe on a base plate for measuring friction loss in a horizontal pipe to study laminar and turbulent flow. Also to find the critical Reynolds number and demonstrate the flow transition point.
