Description
Didactic bench of study of the losses of charges making it possible
to study the regular and singular losses of loads in the hydraulic
networks. The open design of the bench and its wide format make it
an ideal tool for working with large groups of students or pairs in
practical work.
Supplied with a complete instructional manual with practical work
(TP).
Educational holdings
This teaching equipment makes it possible to carry out the
following practical exercises:
- Pressure drop in straight pipes.
- Loss of charge in a sudden enlargement
- Loss of charge in a sudden narrowing
- Pressure drop in elbows (trade and sharp angle)
- Pressure loss in different types of valves
- Pressure loss in curves of different radii
- Flow in a rough pipe (optional)
Supplied with a complete instructional manual with practical work
(TP).

VERTICAL BENCH FOR THE STUDY OF FLUID DYNAMICS
The bench must allow the following pedagogical operations:
- Pressure drop in straight pipes.
- Loss of charge in a sudden enlargement
- Loss of charge in a sudden narrowing
- Pressure drop in elbows (trade and sharp angle)
- Pressure loss in different types of valves
- Pressure loss in curves of different radii
- Flow in a rough pipe (optional)
Technical specifications required:
- The bench should allow the study of pressure losses in pipes,
elbows and valves.
- It will consist of two piping circuits with a common inlet and
outlet. These two circuits will have different diameter pipes and
will include straight lengths, elbows, contractions, widenings, a
valve and a ball valve.
- The pressure differences will be measured by piezometric tubes
with back pressure, graduated in mm.
- For the valves, the pressure will be measured by a needle gauge
