Pipe2018: Gas analyzes steady, one-dimensional, isothermal flow for ideal and non-ideal variable density gases.
The model includes the ability to account for temperature variations, ideal natural gas distribution and landfill gas collection. It is also useful for determining the effects of demand or load changes.
Pipe2018: Gas can accommodate large networks, looped systems and multiple supply and load points. Several scenarios may be set up in a single model, such as load changes and open/closed valves.
Darcy Weisbach equations and the Ideal Gas law are used to describe pressure-temperature density relationships. Non-Ideal Gas and Constant Density Gas analyses are also available. Mass-flow calculation is used to determine velocity.
