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 bench
