Jet Trajectory and Orifice Flow
Product Code : LSK-FM-10470
Jet Trajectory and Orifice Flow (SKU LSK-FM-10470) combines two classic hydraulics experiments in one bench-top unit: measuring the coefficients of an orifice and plotting the path of a free water jet. Engineering and polytechnic students use it in fluid mechanics lab experiments on the hydraulic bench. It is manufactured at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, where Science Lab Supplies produces it for direct supply to colleges, tender contractors and distributors.
Specifications
A transparent cylindrical tank receives water from the hydraulic bench through an adjustable diffuser, and an overflow pipe holds a steady head. Four interchangeable nozzles with different orifice designs fit the base vertically, or horizontally for trajectory work, while manometers, a Pitot traverse and a sharp blade measure the jet.

Applications and Experiments for the Jet Trajectory and Orifice Flow Apparatus
Students measure how much the flow, energy and stream area fall as water leaves each nozzle, giving the coefficients of discharge, velocity and contraction, then trace horizontal jets onto graph paper. These practicals appear in B.Tech/B.E. civil and mechanical fluid mechanics labs and diploma hydraulics courses.
- Coefficient of discharge of four orifice designs at different heads.
- Coefficient of contraction from the jet diameter measured with the sharp blade.
- Coefficient of velocity from Pitot readings and from the jet trajectory.
Standard Scope of Supply
The unit is supplied with the transparent tank, diffuser and overflow pipe, four interchangeable nozzles, the base bung, manometers, the Pitot traverse assembly, the sharp-blade jet gauge and the plotting board with depth gauge pins. The hydraulic bench that feeds it and measures the flow is a separate item.
Packing, MOQ and Lead Time
Science Lab Supplies quotes one unit or a number of units for parallel student groups, and states packing, delivery time and price for that quantity on the quotation. A hydraulic bench and other engineering lab equipment in India can share the quotation.
Holding an Importer-Exporter Code, the company can ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. Ask for a quotation from the contact page, place the item in the enquiry cart, or refer to the lab tender page for tender supply.
Frequently Asked Questions
How is the head on the orifice changed?
The level in the tank is set by the inflow and an overflow pipe. Students change the flow to the diffuser to raise or lower the level, and so the head on the orifice.
How is the jet trajectory recorded?
A nozzle is fitted in the horizontal mounting and the base sealed with a bung. Students then use the plotting board and depth gauge pins to mark the jet profile onto graph paper.
How does it differ from Flow Through an Orifice?
Flow Through an Orifice is supplied with a sharp-edged orifice mounted in its tank. This model adds four interchangeable nozzles, a horizontal mounting and a plotting board for trajectory work.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies builds this apparatus in-house at its factory in Saha, Ambala, India, and sells it directly rather than through traders.
Related Hydraulic Bench Experiments
These bench-top units share the hydraulic bench with this apparatus and follow on naturally from orifice work: a simpler orifice rig, the bench itself, a Venturi study of Bernoulli's theorem and a jet-force experiment that uses the same kind of free jet.
