General Description

The free discharge apparatus allows for investigating the effect of different discharge contours on the pressure loss of a freely discharged jet.
The apparatus comprises transparent tank with adjustable over flow and a set of measuring instruments essential to determining parameters related to the phenomena.
The apparatus could be fitted with 5 interchangeable discharge inserts, and has been designed to be accommodated on the top working surface of the fluid mechanics bench, with water supply flow it and flow rate to be measured by the flow meter of the bench.
The apparatus incorporates a jet diameter measuring device, twin tube manometer, and a pitot tube.
