Complex Pipe Systems Handling Natural or similar Gas

Complex Pipe Systems Handling Natural (or similar) Gas 

The method suggested in the Bureau of Mines Monograph No. 6 [43] has found wide usage, and is outlined here using the Weymouth Formula as a base. 

Determine the equivalent length of 25 miles of 10-in. (10.136-in. I.D.) which has a parallel loop of 6 miles of 8-in. (7.981-in. I.D.) pipe tied in near the midsection of the 10-in. line. 

This value of d0 may be used directly in the Weymouth formula.
