Figure 69  Isometric Gas 03 – Looped Gas Pipeline

A pipeline constructed over a hilly terrain has a looped middle section and is used to transport 112 MMSCFD of natural gas from point A To Point F, which are 41.5 miles apart.


The looped section is constructed on the side of a hill. Point D has an elevation of 2300 ft and Point C (further downhill) has an elevation of -200 ft, relative to the start datum. 


Calculate the final delivery pressure.
