Description

In the Orifice & Free Jet Flow accessory a constant head tank is 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 and is indicated by a level scale. A jet trajectory tracing device allows the path followed by the jet to be ascertained.

Adjustable feet permit levelling.
