详细介绍

Compares pressure losses and k value of popular fittings in small-bore pipework.


Key Features 

• Compact, easy to fit and easy to use 

• Direct comparison of pressure loss across different pipe fittings and their k value 

• Includes three different bends - mitre, elbow and large radius 

• Compares losses in a sudden enlargement (or expansion) and a contraction 

• Includes a multi-tube piezometer for fundamental, accurate pressure measurements 

• Works with TecQuipment’s Hydraulic Bench for easy installation and use 


Learning Outcomes 

• Measurement and comparison of losses in pipework bends 

• Measurement and comparison of losses in a pipework expansion and contraction


Key Specifications 

• Mitre and elbow bends 

• Large radius bend 

• Sudden expansion 

• Sudden contraction 

• Downstream control valve 

• Ten pressure tappings


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)* 

*This product will also work with existing TecQuipment Gravimetric and Volumetric Hydraulic Benches (H1 and H1D)
