Description: Direct measurement of total head, head loss and diameter of a vertical water jet. Integral Pitot traverse with blade to measure head in the jet and diameter of jet. Includes a sharp-edged circular, triangular and square orifices. Also converging/diverging, angled entrance and exit, curved entrance (parallel throat) nozzles.
Specification:
Includes 13 mm diameter sharp-edged orifice.
Integral Pitot traverse.
Sharp-edged Orifice: 13 mm diameter.
Circular orifice dimensions:
1.Length 13 mm, with 60°contraction and 60° diverging section.
2.Length 13 mm, with29 mm diameter bell-mouth approach to 60° diverging section.
3.Length 60 mm, with 29 mm diameter bell-mouth approach to 51 mm long parallel section.
4.Length 60 mm, with 29 mm diameter bell-mouth approach, to 30° diverging section and 25 mm long parallel section.
Triangular Orifice Dimension:
1.Each side nominally 12.1 mm, including 1.5 mm corner radius.
2.Square Orifice Dimension: 9 mm square.
3.Orifice Material: Aluminum.
Experiment:
1.Investigations into a variety of orifices over a range of flowrates.
2.Determination of contraction and velocity coefficients.
3.Calculation of discharge coefficient.
4.Determination of actual discharge coefficient, and comparison with calculated values.
5.Determination of the various coefficients over a range of flowrates to demonstrate the influence of Reynolds number.
6.Study of the characteristics of different orifices, using a set of four circular orifices (nozzles).
7.Each has the same minimum throat diameter but a different length.
8.Each has a different approach and discharge section.
9.Also included are additional square and triangular orifices.
10.Study of the characteristics of different orifices.
