Pressure performance behaviour is often counter-intuitive and is one of the key reasons for modelling. Pressure performance plots highlight the impact of multiphase flow in hilly terrain pipelines. In many operating scenarios, the lowest pressure loss occurs when a “medium” sized line is used. If larger lines are used, liquid loading occurs and increasing hydrostatic pressure losses cause the overall pressure loss to increase. If smaller lines are used, increasing frictional pressure losses cause the overall pressure loss to increase.
