Consider a 10 mile natural gas pipeline with an outer diameter of 12 in (0.25 in. wall thickness). The pipe is transporting 100 MMSCFD of gas with specific gravity 0.60 at an average temperature of 80 F, the inlet pressure is 1,400 psia. What is the outlet pressure?
You may solve this using the Weymouth equation. Assume an average gas compressibility of 0.93.
Elevation changes are ignored.
