 The results and underlying principles of the study of pipe friction are of the greatest

importance to engineers in the aeronautical, civil, mechanical, marine, agricultural and hydraulic fields. This apparatus allows the detailed study of the fluid friction head losses which occur when an incompressible fluid flows through pipes, bends, valves and pipe flow metering devices. Friction head losses in straight pipes of different sizes can be investigated over a range of Reynolds' numbers from 103 to nearly 105, thereby covering 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.

Experimental Capabilities:  

  • To determine the relationship between head loss due to fluid friction and velocity for flow of water through smooth bore pipes and confirm the head loss predicted by pipe friction equation

  • To determine the relationship between fluid friction coefficient and Reynolds' number for flow of water through a pipe having a roughened bore

  • To determine the head loss associated with flow of water through standard fittings used in plumbing installations

  • To demonstrate the application of differential head devices in the measurement of flow rate and velocity of water in a pipe

  • Pumps are used in almost all aspects of industry and engineering from feeds to reactors and distillation columns in chemical engineering to pumping storm water in civil and environmental.

Centrifugal pump is widely used because they are very quiet, they have a relatively low operating and maintenance costs, they take up little floor space and create a uniform and non-pulsating flow.

This apparatus is specially designed to demonstrate to students the operating characteristics of centrifugal pump in series, parallel or single pump operation.

Experimental Capabilities 

  • To demonstrate the basic operation and characteristic of centrifugal pumps.

  • To differentiate the performance curve of a single pump and of two identical pumps that are run in series or parallel.
