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 unit that stands on the hydraulic bench worktop: measuring the coefficients of an orifice and plotting the path of a free water jet. It suits fluid mechanics lab experiments for engineering and polytechnic students. Science Lab Supplies makes this two-in-one apparatus in Ambala, India, at Plot 448, HSIIDC Industrial Area, Saha, and invoices colleges, tender contractors and distributors directly from the works.
Specifications
The four-nozzle orifice tank is described fact by fact in the table that follows. In short, a transparent cylindrical tank receives bench water through an adjustable diffuser while an overflow pipe holds the head; interchangeable nozzles fit the base vertically, or horizontally for trajectory work, and 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, set against weir discharge measured on Discharge Over a Notch.
- Coefficient of contraction from the jet diameter measured with the sharp blade.
- Coefficient of velocity from Pitot readings and from the jet trajectory.
- A school-level lead-in is the Fluid Pressure Apparatus (Spouting Cylinder), whose three equal orifices at different heights show pressure rising with depth.
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. Mention the nozzle set and bench you plan to use when you write on the contact page, or simply add the unit to the enquiry cart; the lab tender page serves tender buyers.
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?
Every Jet Trajectory and Orifice Flow unit leaves the Science Lab Supplies factory in Saha, Ambala, India, and the company quotes it to you itself instead of passing the enquiry to a trader.
