    A function of Reynolds number only
  • b)
    A function of d/D only
  • c)
    A function of d/D and Reynolds number

An orifice meter provides a simpler and cheaper arrangement for the measurement of flow through a pipe. An orifice meter is essentially a thin circular plate with a sharp-edged concentric circular hole in it.
Cd is defined as the ratio of the actual flow and the ideal flow and is always less than one.
For the orifice meter, the coefficient of discharge Cd depends on the shape of the nozzle, the ratio of pipe to nozzle diameter, and the Reynolds number of the flow.
