Orifice Discharge
Product Code : JA-FMAHLE-9954
The Orifice Discharge accessory (SKU JA-FMAHLE-9954) is used on a hydraulics bench to study flow through a small orifice in the base of a cylindrical glass tank. A traversing Pitot tube with a knife edge measures the velocity and diameter of the jet, including the vena contracta, so that the discharge, velocity and contraction coefficients can be found. JaincoLab supplies this orifice discharge unit to engineering colleges and polytechnics.
Specifications
The unit has a cylindrical glass tank with an orifice in its base, a standard orifice and four additional interchangeable orifices with dimensions on a label in their storage case, a traverse carrying a Pitot tube and sharp blade, and manometer tubes for Pitot head and total head.

Applications of the orifice discharge accessory
The orifice discharge accessory lets students measure the jet diameter at the vena contracta and the jet velocity, and from these the coefficients of contraction, velocity and discharge for several orifice shapes, a standard experiment in fluid mechanics.
- Measuring the jet diameter and vena contracta diameter with the knife edge
- Determining the coefficient of contraction
- Measuring jet velocity with the Pitot tube and finding the coefficient of velocity
- Comparing the coefficient of discharge of the five orifices
Scope of supply
The listing covers the glass tank, standard and four additional orifices with storage case, traverse with Pitot tube and knife edge, and manometer tubes. The hydraulics bench and the optional software are confirmed on the quotation. Accessories, spares and quantities are confirmed on the quotation.

Frequently asked questions
How many orifices are supplied?
A standard orifice and four additional interchangeable orifices, kept in a storage case with their dimensions on a label.
How is the vena contracta measured?
A sharp blade on the Pitot tube traverse is moved across the jet to measure its diameter.
Does it need a hydraulics bench?
Yes. It connects to a hydraulics bench with a quick-release fitting; the bench is quoted separately.
What should a quotation request include?
Send the SKU JA-FMAHLE-9954, whether a hydraulics bench and the software are needed, the quantity and the delivery destination.
