Impact of Jet on Vanes Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-FML-10025
Jlab Export is a leading Impact of Jet on Vanes Apparatus Manufacturer,and suppliers in India
Impact of Jet on Vanes Apparatus (code EL-FML-10025) measures the force of a vertical water jet on two brass targets, a flat plate and a hemispherical cup, inside a stainless steel chamber with glass on two opposite sides. The force is balanced with weights on a weight pan and compared with the force predicted by momentum theory. JLab manufactures each jet-impact unit, chamber and targets included, in Ambala, India.

Balancing the Jet Force
Water leaves the nozzle vertically and strikes the target, which is carried on a stem passing up through the cover to a weight carrier. A compression spring takes the dead weight of the moving parts, so with no flow the mark on the weight pan lines up with the level gauge. When the jet strikes, the target is pushed up; weights are added to the pan until the mark returns to the gauge, and their total weight equals the vertical force of the jet.
Momentum Theory for the Plate and the Cup
The jet velocity v is the discharge Q, from the measuring tank and stopwatch, divided by the nozzle area a. Momentum theory gives F = ρ a v² (1 + cos θ), where θ is the angle between the water leaving the target and the direction opposite to the jet. The flat plate turns the water through a right angle (cos θ = 0), so F = ρ a v²; the hemispherical cup sends it back almost along its path (cos θ close to 1), so the ideal force nearly doubles to 2ρ a v². Measured forces come out a little lower because of friction on the target and the slowing of the jet as it rises from the nozzle to the target.
