Objective To determine the force generated by a jet of water striking on a surface Description of apparatus The supply is led to a vertical pipe terminating in a tapered nozzle. This produces a jet of water which impinges on the vane in the form of a Flat Plate, Hemispherical Cup, Conical Plate or 30° Angled Plate. The nozzle and vane are contained within a transparent cylinder; at the base of the cylinder there is an outlet by which the...
