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.
