Quick Answer: Impact Of Jet On Vanes Apparatus measures the force of a water jet striking a flat plate and a hemispherical cup and compares it with the force predicted by momentum theory. The jet issues vertically from a brass nozzle inside a stainless steel chamber with glass sides.

About This Product
The target sits on a stem that passes through the cover to a weight carrier, with a compression spring counterbalancing the dead weight of the moving parts. Weights are added to the pan until its mark lines up with the level gauge, giving the vertical force of the jet. Comparing that force with momentum theory for the flat plate and the hemispherical cup is the core exercise this engineering lab equipment in India brings to the FLUID MECHANICS LAB.
Frequently Asked Questions
Q1. How is the jet force measured? Weights are added to the weight pan until the mark on the pan corresponds with the level gauge; the added weights give the vertical force on the target.
Q2. Which targets are supplied? Two brass targets: a flat plate and a hemispherical cup.
