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.
