H4 A stopwatch Teaching device for studying a flow through an orifice educational lab equipment Hydrodynamics Lab

Description

A didactic apparatus for studying a flow through an orifice for studying a flow of water through a vertically mounted orifice.

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:

– Determination of contraction and speed coefficients

– Calculation of the flow coefficient

– Determination of the actual flow coefficient and comparison with the calculated values.

– Determination of the different coefficients for different flow rates in order to show the influence of the Reynolds number.

Supplied with a complete instructional manual with practical work (TP).

Specifications for tender

APPARATUS FOR STUDYING FLOWS THROUGH AN ORIFICE

The bench must allow the following pedagogical operations:

– Determination of contraction and speed coefficients

– Calculation of the flow coefficient

– Determination of the actual flow coefficient and comparison with the calculated values.

– Determination of the different coefficients for different flow rates in order to show the influence of the Reynolds number.

Technical specifications required:

– Cylindrical glass tank with orifice at the bottom of this tank.

– The water supply of the tank will be done through a diffuser.

– The vertical jet flows into the bench flow measurement tank.

– A pitot tube, with traversing device can be positioned anywhere in the jet. A thin-edged blade attached to the Pitot tube will measure the width of the jet and thus determine the contraction coefficient.

– The pressure under the jet with the pitot tube and the total pressure above the orifice will be indicated by pressure tubes placed next to the tank.

– Manometric scale 100 mm to 390 mm
