H4 A stopwatch Teaching device for studying a flow through an orifice - H4 Fluid Mechanics Laboratory Vocational Training Equipment
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
- 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
