Modelling issues
Compressibility, line pack (i.e. storage inside pipes), gas consumption of compressors, daily modelling, Gross Calorific Value (GCV), storage, LNG transport
Compressors are needed to maintain pressure throughout the network. They are typically stationed every 90 km to 150 km in the long-distance network, sometimes up to every 400 km for international routes [Rövekamp]. Onshore long-distance pipelines have a diameter of 0.4 to 1.4 meters and pressures up to 100 bar [Rövekamp]. The compressors can consume up to 5-10% of the transported gas (0.3% per 150 km? citation needed).
It's apparently hard to measure exactly what is flowing at any one time in the network; often only daily flows are modelled or reported.
The Weymouth equation is an approximation used to calculate the flow in the pipe based on the pressures at either end. It is generally used for high-Reynolds-number flows where the Moody friction factor is merely a function of relative roughness.
The relation between pressures p_{m,n} at m,n and flow f_{mn} is given by:
f_{mn} = sgn(p_m,p_n) C_{mn} \sqrt{|p_m^2 - p_n^2|}
where sgn(p_m,p_n) =1 if p_m \geq p_n and sgn(p_m,p_n) = -1 if p_m < p_n.
