Forced Vortex Flow Manufacturer,Supplier and Exporter in India
Product Code : EL-ELA-5513
Jlab Export is a leading Forced Vortex Flow Manufacturer,and suppliers in India
Forced Vortex Flow (code EL-ELA-5513) is fluid mechanics teaching apparatus in which a motor-driven cylinder of water is rotated about its axis to form a forced vortex with a parabolic free surface. Students read the surface profile by traversing a Pitot-static tube along a radius, then repeat the run at a second motor speed. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Vortex Apparatus?
| Model | Vortex types | Listed details |
|---|---|---|
| This apparatus (EL-ELA-5513) | Forced vortex | Motor-driven rotating cylinder; Pitot-static tube traversed along a radius; single phase 220 V, 50 Hz, 5 A |
| Forced Vortex Apparatus | Forced vortex | Transparent cylindrical tank rotated by a variable speed motor through a V belt; probe traversed horizontally and vertically across the full diameter on graduated axes; drain arrangement |

Choose this apparatus for the forced-vortex experiment with Pitot-static surface readings; the Free and Force Vortex Apparatus suits courses that also cover the free vortex in the same unit.
What Is the Forced Vortex Flow Apparatus Used For?
A forced vortex is rotational flow: when a cylinder of fluid is turned about its axis, or a paddle is rotated in a large volume of fluid, every particle moves with the same angular velocity once conditions are steady, so there is no relative motion between particles. The streamlines are concentric circles, and the total energy is constant along each streamline but varies from one streamline to the next. The free surface becomes a paraboloid whose height rises with the square of both the radius and the angular speed, which students check against their measured profile.
The listed experiment fills the cylinder with water to about half its height and rotates it at a constant, reasonably fast speed. Once conditions are steady, the speed of rotation is measured and the surface profile is read by traversing the Pitot-static tube along a radial line, taking the elevation at r0 as the datum; the motor speed is then changed and the readings repeated. It is a standard fluid mechanics and hydraulics lab experiment in mechanical, civil and chemical engineering degree and diploma courses.
The listing’s care notes are to avoid running it below 180 V, keep it free of dust, use clean water, grease or oil the rotating parts once in three months, and drain it completely if it will stand unused for more than a month.
What to Specify When Ordering
- Quantity — the minimum order is 10 units.
- Site utilities — single phase 220 V, 50 Hz, 5 A with earth, plus a water supply and drain; mention it if your laboratory supply differs.
- Other fluid mechanics experiments — Pitot tube and Bernoulli’s theorem apparatus are separate items that can be quoted on the same enquiry.
Frequently Asked Questions
What shape does the water surface take?
A parabolic profile. In a forced vortex every particle turns at the same angular velocity, so the surface rises with the square of the distance from the axis.
How is the surface profile measured?
With a Pitot-static tube immersed just beneath the water surface and traversed along a radial line, using the surface elevation at r0 as the datum for all readings.
Can the rotation speed be changed?
Yes. The listed procedure takes a second set of readings after the speed from the motor has been changed, so students can compare profiles at two speeds.
How does it differ from the Free and Force Vortex Apparatus?
That unit adds four circumferential jets and an orifice reducing bush for free-vortex experiments in the same acrylic cylinder; this apparatus is listed for the forced vortex only.
What information is needed for an export quotation?
Send the quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling needs, and the tender reference if the order is for a tender.
Who manufactures this forced vortex apparatus?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, builds it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of engineering and science lab equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The vortex apparatus is assembled at JLab’s own works rather than bought from a trader, so engineering institutes, dealers and importers buy it factory-direct, each unit is visually inspected before dispatch, and repeat orders are handled by the maker. JLab exports worldwide and ships to buyers in every region — for example Brazil in South America, the UAE in the Middle East, Chad in Central Africa, New Zealand in Oceania and Guinea in West Africa. For tenders, see the JLab lab tenders page.

- Free and Force Vortex Apparatus — free and forced vortex in one acrylic cylinder.
- Pitot Static Tube Set-Up — point velocity and velocity profile in a pipe.
