Linepack effect

NettetThe linepack is defined as the increase in volume of the water/liquid present in the pipeline due to compressibility of water/liquid and elasticity of the pipeline at any time. Importantly, linepacking represents the major energy loss gradient only in liquid pipelines and not applicable for gaseous flows. NettetDue to the linepack (buffer effect) in our network, it is possible that a change in the gas flow on the exit side of our network will be followed at a later moment by a …
