A fluid flowing in a pipe is subjected to a friction force which causes a loss of energy and thus a total pressure drop. This varies according to the obstacles that the fluid encountered. We distinguish the regular pressure losses, due to friction on the walls of pipes and singular pressure losses caused by the singularities of the network (elbows, valves ...). The MP76 bench allows to highlight these different regular and singular pressure drops due to the main elements of installation piping. The transparency of the pipes and the pressure-reducing devices makes it possible to visualize the flows (laminar and turbulent regimes) by dye injection.

  • Visualization of flows in pipes and pressure-reducing devices
  • Detection of laminar and turbulent flow regimes according to flows and pressures
  • Study of the regular pressure losses of: Pipes of different diameters; Smooth and rough pipes; Pipes rising, descending and inclined
  • Study of the singular pressure losses of: Elbows of different radii; Abrupt increase and decrease in the diameter of a pipe; Different valves
  • Measurement of flow rates by vacuum devices (venturi, diaphragm)
  • Determination of the Kv of the valves

Designed and manufactured industrially, this bench operates in a closed circuit using a pump and a feed tank. It is completely autonomous, requiring only a power supply. It can be easily used in a workshop or classroom. A complete instrumentation is provided with the bench for the measurement of the upstream and downstream pressures of each of the elements allowing the determination of the regular and singular pressure losses, the measurement of the flow by the pressure-reducing members and the determination of the coefficient Kv of the valves.
