Calculate Total Head Loss Between Two Points

Question

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)

Tee
                                                            0.6 (Straight-through flow)

1. 8 (Side-Outlet Flow)

90° Elbow                                                                   0.30

Summary

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.
