Orifice and Free Jet Flow Description and Specifications for Lab Tenders
Orifice and Free Jet Flow.
Orifice and Free Jet Flow
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 series of adjustable probes allow the path
followed by the jet to be ascertained. Adjustable feet permit
levelling.
Experimental Capabilities:
Establishing the coefficient of velocity for a small orifice.
Finding
experimentally 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 mechanic
Specifications:
Orifice diameters: 3.0mm and 6.0mm
Jet trajectory probes: 8
Max. constant head: 410mm
Quick release fitting for easy connection to hydraulics benchÂ
