FRICTION LOSS IN A PIPE

The Friction Loss in a Pipe apparatus allows students to study the change in the laws of resistance for laminar to turbulent flow and find the critical Reynolds number. The apparatus shows the flow transition point from laminar to turbulent, and is ideal for demonstrations as well as student experiments.
The equipment is a small-bore, straight test pipe on a base plate. It works with TecQuipment’s Digital Hydraulic Benches (H1F, available separately).

Static pressure tappings upstream and downstream of the test pipe connect to a water manometer or a hand-held digital pressure meter (supplied). The back panel holds the manometer with calibrated scales. The water manometer measures lower differential pressures in the laminar and lower turbulent flow regions (just above the critical Reynolds Number). The pressure meter measures higher pressures in the turbulent flow region. The water manometer includes an air valve and hand-pump. The hand-pump adjusts the datum of the water manometer where necessary. A precision needle valve downstream of the test pipe accurately controls flow rate.

To perform experiments, students stand the apparatus on the hydraulic bench and fit the Header Tank (supplied). For low flow rate experiments, the Header Tank supplies the test pipe. For higher flow rate experiments, the hydraulic bench supplies the test pipe directly. Students set the flow rate, measuring it by timing the collection of water in a measuring vessel (included).

Students take readings of temperature from a thermometer (supplied) and readings of head from the manometer or the pressure meter. They then use the results to produce charts to help compare actual results with theory.

Study of friction loss in a pipe, including:

  • Investigations of laminar and turbulent flows
  • Demonstration and measurement in a change of the laws of resistance (friction factor) from laminar to turbulent flow
  • Finding the critical Reynolds number
  • Verifying Poiseuille's Equation and the coefficient of viscosity for water in the laminar flow region
Case Study
The University of Regina Returns to TecQuipment Decade After Decade

Repeatability and longevity are just a couple of the reasons why the University of Regina keeps returning to TecQuipment for engineering teaching equipment. This University in the Canadian province of Saskatchewan has been purchasing TecQuipment teaching products from the company since the late 1960s.
