Look at figure below and use. Water (50°F) flows at 250 gpm through the pipe system at the bottom of this page. All piping is four inch (4”) diameter cast iron. The distance between points A and B along the open flow path is 500 ft. Calculate the total head loss between points A and B. Assume A and B are at the same elevation. Use the following minor loss coefficients for the fittings:
Fitting Minor Loss Coefficient
Open Valve 0.20
90° Smooth Bend 0.35 (r/d = 1)
0.19 (r/d = 2)
0.16 (r/d = 4)
0.21 (r/d = 6)
0.28 (r/d = 8)
0.30 (r/d = 10)
Teeâ€¨ 0.6 (Straight-through flow)
90° Elbow 0.30
The question belongs to Chemical Engineering and it discusses about calculating the total head loss between the two points A and B. The solution discusses this in more detail.
