FM-HBA-24 FLUID FRICTION APPARATUS (HYDRAULIC BENCH ACCESSORIES) ​

The unit consists of a tubular steel framework which supports the network of pipes and fittings for test. Pipe friction experiments are carried out using four smooth pipes of different diameters, plus one roughened pipe. Short samples of each size test pipe are provided loose so that the students can measure the exact diameter and determine the nature of the internal finish. A system of isolating valves is provided whereby the pipe to be tested can be selected without disconnecting or draining the system. A selection of pipe fittings and valves are fitted around the network and are fitted with pressure tapings. A clear acrylic pipe section incorporates a Venturi, orifice plate and Pitot tube. Pressure tappings are fitted with quick action self-sealing connections. Probe attachments are provided with tubing so that any pair of pressure tapings can be rapidly connected to appropriate instrumentation, eg. a manometer

• 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
