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

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.

It works with Digital Hydraulic Bench. 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.

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

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.
