Impact of a Jet Apparatus
Product Code : EL-FMLE-10666
QUICK ANSWER: The Impact of a Jet Apparatus is used to measure the vertical force exerted by a water jet on a target surface and to compare it with the force predicted by momentum theory. It consists of a cylindrical tank with lateral transparent surfaces, a discharge nozzle (8 mm diameter) connected to the Hydraulics Bench and aligned with an interchangeable target surface (40 mm diameter) – a 90° flat surface, a 120° curved surface, or a 180° hemispherical surface; the dead weight of the moving parts is counterbalanced by a compression spring, and the vertical force is measured by adding calibrated weights (5, 10, 50 and 100 g, supplied) to a weight pan until a mark on the pan aligns with a previously zeroed level gauge. Base holes drain the water and prevent splashing, and the apparatus can be mounted on the top surface of the fluid mechanics bench, with flow rate read from the bench's own flow meter via fast, quick-coupling connectors.
The Impact of a Jet Apparatus module consists of a cylindrical tank with lateral transparent surfaces where a nozzle, connected to the Hydraulics Bench, is aligned with a device in which the target surface is fitted. The vertical force made by the water against the surface is measured using calibrated weights that balance this force. Taking as a reference a gauge, which has been previously adjusted to a zero reference, the force is measured thanks to a mark that appears on the surface where the masses were placed. The dead weight of the moving parts is counterbalanced by a compression spring, and the vertical force exerted on the target plate is measured by adding the weights supplied to the weight pan until the mark on the weight pan corresponds with the level gauge. Holes made on the tank base allow the water to drain, and in this way splashes are avoided.
