This orifice application analyzes the flow through orifice for the simulation and design purposes. Based on the AGA Report No. 3[1], it provides following solutions to the questions regarding a orifice and metering:
•The flow rate through an orifice
•The required orifice diameter
•The differential pressure
•The Run diameter at Beta = 0.7 and 50” water column
Besides, the fully recovered downstream pressure is presented. For the gas flow through the orifice, the critical flow is checked and modified automatically.
This application is designed for both liquid and natural gas.
