GASWorkS uses a Newton-Nodal, iterative method of solution. It supports
a number of flow equations including the AGATurbulent, Colebrook, IGT-Improved,
Mueller High and Low-Pressure, Oliphant, Panhandle-A, Panhandle-B, Pole
Low- Pressure, Spitzglass High and Low-Pressure, and Weymouth equations.
The solution routine allows the flowing temperature to be calculated
based on environmental heat loss and gain. Gas properties at a specific
location , including specific gravity, viscosity, ratio of specific heats,
and heating value, can be calculated based on the gas composition. Mixed
gas properties throughout the system can be calculated based on the flow
distribution. Compressibility can be calculated using one of several methods,
including the latest revision of AGA 8.
