Flow through a submerged orifice may be computed by applying Bernoulli’s equation to points 1 and 2 in figure belowValues of C for submerged orifices do not differ greatly from those for nonsubmerged orifices.AdvertisementsShare this postKanwarjot Singh Kanwarjot Singh is the founder of Civil ...
The value of the discharge coefficient parameterizing the two-stage orifice flow equation is primarily based on that of the single classic orifice; however, this assumption leads to significant errors, because of the different numbers in the sudden contraction structure. Through theoretical derivation,...

The factors affecting the flow of granular solids through orifices of different diameter and shapes under gravity conditions has been investigated at various heads. Different granular materials such as sand, sugar, rape seed, wheat and rice were used and the best equation was found to be:— where...

As the fluid flows through an orifice, the pressure drops across the pipe. This phenomenon is also used to measure fluid characteristics. Mathematically, the orifice flow equation gives the mass flow rate (or discharge) QQ through an orifice, given the area of the orifice, AA, and can be ...

Another identical orifice will create an identical pressure drop, another Y bar. Put two such orifices in your circuit and the pressure needed to drive the original flow through your circuit will increase by the sum of the two pressure drops, i.e., 2Y bar. However, something non-linear ...
A pressurized water system may be subjected to high pressure surges because of the expulsion of a trapped air pocket through an orifice at the downstream end of the pipe. Results are presented of laboratory experiments, in which pressure histories were recorded for different upstream heads, air po...
