F1-17 Orifice and Free Jet Flow

 

F1-17 Orifice and Free Jet Flow

A constant head tank is maintained with water from the Hydraulics Bench. The orifice (3mm or 6mm) is installed at the base of this tank ensuring a flush inside surface. The jet trajectory is mapped using 8-point gauges to determine the discharge coefficient.

Description

The Orifice & Free Jet Flow accessory incorporates a constant head tank fed with water from the hydraulics bench. The orifice is installed at the base of this tank by means of a special wall fitting which provides a flush inside surface.

The head is maintained at a constant value by an adjustable overflow pipe and is indicated by a level scale. A series of adjustable probes enable the path followed by the jet to be ascertained.

Adjustable feet permit levelling.
