Description
This compact bench-top apparatus uses smooth, industrystandard plastic pipe, commonly used in domestic and other small-bore water systems.
It works with TecQuipment’s Digital Hydraulic Bench (H1F, available separately)*. The 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. The valve is downstream, so it does not cause any upstream turbulence.
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.
Essential Base Unit
• Digital Hydraulic Bench (H1F)*
