You are here: Home / Mechanical Engineering / Hydraulics / Fluid Dynamics / HORIZONTAL FLUID FRICTION PLANT MP76


A fluid circulating in a pipe circuit is subjected to a frictional force which causes a loss of energy and thus a total pressure drop. The pressure drop varies according to the resistances which the fluid meets. The regular pressure losses due to friction on the walls of the conduits can be distinguished from the losses caused by the individual resistances of elements in the circuit. (elbows, valves...).

MP76The bench for the study of fluid dynamics MP76, makes it possible to quantify the various losses due to the principal elements met in an installation of piping.

The transparency of the conduits and the pressure reducing orifices allows a perfect visualization of the flows, as well as the visualization of the modes of laminar flow and turbulent. This bench is composed of industrial elements placed on a mobile frame. It functions in closed loop by means of a pump and a storage tank. It is self - contained, requiring only a suitable power supply.

It can be thus easily used in a workshop or a classroom and is easily transported. A various instrumentation is provided with the bench for the measurement of the pressures upstream and downstream of each element and thus for the determination of the regular and individual pressure losses, the flow measured by the pressure reducing orifices and coefficient Cv of the valves.

Teaching objectives
