Description

The Fluid Friction Measurements unit provides facilities for the detailed study of fluid friction head losses, which occur when an incompressible fluid flows through pipes, fittings and flow metering devices.

Pipe friction is one of the classic laboratory experiments and has always found a place in the practical teaching of fluid mechanics. With this unit, friction head losses in straight pipes of very different sizes can be investigated over a range of Reynolds’ numbers from10³ to nearly 10⁵. This covers the laminar, transitional and turbulent flow regimes in smooth pipes.

In addition an artificially roughened pipe is supplied, which at the higher Reynolds’ numbers shows a clear departure from the typical smooth bore pipe characteristics.

In addition to the equipment for the study of losses in straight pipes, a wide range of accessories are included such as pipe fittings and control valves, a Venturi tube, an orifice plate assembly and a Pitot tube.

The experimental unit is compatible with the Hydraulic Bench (S1-FM-101). The water is supplied and the flow rate measured by. Alternatively, the experimental unit can be operated by the laboratory supply.
