Energy Dissipation and Limiting Discharge with Orifices
ASCE Pipeline Division Journal
Equations and methods are presented to calculate the energy dissipation and the limit of maximum choked flow for orifices and sudden enlargements. A correction factor Cfis introduced to correct the head loss equation to allow the calculation of maximum choked flow. Equations are given to estimate and calculate Cf. The difference between the use of an orifice as a flow meter and an energy dissipator is emphasized
