AH4 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).

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
– Maximum load: 365 mm
– Maximum flow: 13 liters per minute
– 13 mm Thin Wall Circular Orifice in Aluminum
– Dimensions: approx 720 mm x 520 mm x 470 mm
– User and Practical Manual in French
