## 一般說明

The Bernoulli's Theorem Demonstration unit, "FME03", designed by EDIBON is mainly composed of a circular section pipe with the shape of a truncated cone, transparent and with seven pressure taps that allows to measure, simultaneously, the static pressure values corresponding to each section.

All the pressure taps are connected to a manometer with a water collector (water might be pressurized).

The ends of the conduits are removable, enabling to be placed in either convergent or divergent form with respect to the stream direction.

There is also a probe (Pitot’s tube) moving along the conduit for measuring the height in every section (dynamic pressure).

The flow rate and the pressure in the unit can be modified by adjusting the control valve located at the end of the unit.

A flexible hose attached to the outlet pipe is directed to the volumetric measuring tank.

For the operation, the unit is placed on the Hydraulics Bench (FME00).

It has adjustable legs for levelling.

The inlet pipe ends in a female coupling which may be directly connected to the bench supply.
