FLUID Friction Measurement (MODEL ME-FM-1225E-R)

 
The ARL’s 1225E Fluid Friction Measurements unit provides facilities for the detailed study of fluid friction head losses which occur when an in-compressible fluid flows through pipes, fittings and flow metering devices. 
  • A 1225E unit for the detailed study of fluid friction head losses, which occur when an in-compressible fluid flows through pipes, fittings and flow metering devices
  • A substantial floor-standing tubular steel frame supports test circuits comprising:
    – Four smooth-bore pipes of different diameters ranging from 4.5mm ID to 17.2mm ID
    – Artificially roughened pipe
    – 90° bends (large & small radii)
    – 90° elbow
    – 90° mitre
    – 45° elbow, 45° Y, 90° T
    – Sudden enlargement
    – Sudden contraction
    – Gate valve
    – Globe valve
    – Ball valve
    – Inline strainer
    – Perspex venturi
    – Perspex orifice meter
    – Perspex pipe section with a pitot tube & static tapping
    – 38 tapping points
  • All fixed pipes fabricated in stainless steel
  • Suitable for studying Reynolds’ numbers from 103 to nearly 105
  • A system of isolating valves, quick release manometer connection valves and self-sealing pressure tappings ensure fast accurate results
  • Data logging accessory available
  • Computer-aided learning program available
  • A user instruction manual provides installation, commissioning and maintenance data, together with student exercises
  • The unit is designed for use with a Hydraulics bench

A wide range of measurements, demonstrations and training exercises are possible with the equipment:

  • Confirming the relationship between head loss due to fluid friction and velocity for flow of water
  • Determining the head loss associated with flow through a variety of standard pipe fittings
  • Determining the relationship between pipe friction coefficients and Reynolds’ number for flow through a pipe with roughened bore
  • Demonstrating the application of differential head devices in the measurement of flow rate and velocity
  • Providing practical training of pressure measurement techniques
  • Enhancing understanding of the hydraulic principles involved through the use of complementary computer software

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 from 103 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.

An arrangement of six pipes provides facilities for testing the following:

  • Four smooth-bore pipes of different diameters
  • Artificially roughened pipe
  • 90° bends (large & small radii)
  • 90° elbow
  • 90° mitre
  • 45° elbow
  • 45° Y
  • 90° T
  • Sudden enlargement
  • Sudden contraction
  • Gate valve
  • Globe valve
  • Ball valve
  • Inline strainer
  • Perspex Venturi
  • Perspex orifice meter
  • Perspex pipe section with a Pitot tube & static tapping
