Orifice Sizing Principles
An orifice only works well when supplied with a fully developed flow profile. This is achieved by a long upstream length (20 to 40 pipe diameters, depending on Reynolds nuer) or the use of a flow conditioner. Orifice plates are small and inexpensive but do not recover the pressure drop as well as a venturi nozzle does.

The siphon is a small-diameter hose, Example 9: A pressurized tank of water has a 10-cm-diameter orifice at the bottom, where water discharges to the atmosphere. Example 23: A hydraulic turbine has 85 m of head available at a flow rate of 0.25 m3/s, and its overall
On the Flow of a Compressible Fluid through Orifices
orifice the fluid velocity . will . be comparatively small along the reservoir walls, and hence effect of compressibility on the flow pattern actually within the reservoir may be neglected. This assumption will be increasingly valid as the orifice shape approaches that of a Borda mouth-piece from a nozzle-like form.

Discharge Coefficient for Nozzles and Orifices | Neutrium
The discharge coefficient is a dimensionless nuer used to characterise the flow and pressure loss behaviour of nozzles and orifices in fluid systems. Orifices and nozzles are typically used to deliberately reduce pressure, restrict flow or to measure flow rate. This article gives typical values of the discharge coefficient for common orifice and nozzle designs.
