THE ORIFICE PLATE DISCHARGE COEFFICIENT EQUATION …
Although the orifice plate isthe recognized flowmeter for the measurement of natural gas and light hydrocarbon liquids, the orifice discharge coefficient equation inuse inthe international standard ISO 5167-1: 1991 (I) is based on data collected more than 50years ago.

www.sscafca.orgAn orifice is a submerged opening with a closed perimeter through which water flows. Orifices are analyzed using the following equation: Q = CA 2gh where: Q = Discharge in cfs C = Coefficient of discharge from Handbook of Hydraulics, King and Brater, 5th Edition (or comparable) A = Area of opening in square feet g = 32.2 ft/sec

The flow calculations for the long radius nozzle are similar to that of the orifice plate, with the exception of the values of the discharge coefficient.

www.uobabylon.edu.iqCoefficient of discharge is the ratio of actual flow to the theoretical flow and makes allowances for stream contraction and frictional effects. Venturi meter, orifice meter, and Pitot tube are widely used head flow meters in the industry. The Pitot-static is often used for measuring the local velocity in pipes or ducts. For measuring flow in ...
