Gas Pipeline Sizing Reference

AGA Flow Equation

The AGA (American Gas Association) flow equation is widely used for calculating gas flow through pipelines:

Q = C × (Tb/Pb) × (P12 - P22)0.5 × D2.5 × (1/√f)

Where:
Q = flow rate
C = constant
Tb = base temperature
Pb = base pressure
P1, P2 = inlet and outlet pressures
D = pipe diameter
f = friction factor

Panhandle A Equation

The Panhandle A equation is an empirical relationship for turbulent flow:

Q = 435.87 × (Tb/Pb)1.0788 × (P12 - P22)0.5394 × D2.6182 × E

Where:
E = efficiency factor
Other variables same as AGA equation
