NCEES Civil PE Specification Hydraulics and Hydrology: Pressure conduit

Problem

A water distribution system uses a 500 ft long PVC pipe with a Hazen-Williams roughness coefficient of 150. The pipe has a diameter of 1 ft and carries water at a flow rate of 2 cubic feet per second.

Using the Hazen-Williams formula, the head loss \(h_f\) (in feet), is most nearly:

Select an Answer:

A) 0.25 ft
B) 0.50 ft
