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.
Experimental Content:
- Establishing the coefficient of velocity for a small orifice
- Finding the coefficient of discharge for a small orifice with flow under constant head and flow under varying head
- Comparing the measured trajectory of a jet with that predicted by simple theory of mechanics
- Effect of tank level on jet outlet velocity
Technical Specification:
- Orifice diameters: 3.0mm and 6.0mm
- Jet trajectory probes: 8
- Max constant head: 410mm
