Question

An existing 10-inch PVC line (C = 130) is designed to carry 900 gal/min. A new development wants to use this line for their water service which means the existing 10-inch line needs to convey an additional 500 gal/min, for a total flowrate of 1400 gal/min. The water utility standards state that the unit headloss can not exceed 5 ft/1000 ft. Will this new development cause the pipeline to exceed its capacity? Please show your work answering this question.

ANSWER

Given data

The diameter of the piped d = 10in

The total flowrate Q = 1400gal/min

C = 130

consider the pipe length L = 1000ft
