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 encounters. 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 bench for the study of fluid dynamics, MP75D, makes it possible to highlight these different regular and singular pressure losses due to the main elements encountered in a pipe installation. The transparency of the pipes and the pressure-reducing devices makes it possible to perfectly visualize the flows, in particular to visualize the laminar and turbulent flow regimes.
- Study of the main elements encountered in a pipe installation
- Measurement of the pressure losses generated by these different elements by means of a differential pressure sensor with display and quick couplings
- 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
- Study of singular and linear pressure drops: bends 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
