Question about Six-minute Geotech(2nd edition) Prob 38

[jerome]

Good Day!

I solved six-min Geotech(2nd Edition) Prob 38, but i don't understand this solution.

I think that "dh1 +dh2 = 12ft" is wrong.

Total loss head is "(12+15) - 12 = 15ft"

Therefore, "dh1 + dh2 = 15ft" is right.

What do you think about that?

Wow, I just checked my Six-Minute Solutions (Geotechnical) for problem 38 and the problem solution is correct; it shows dh1 + dh2 = 15-ft. That is the correct answer set-up for evaluating the headloss in the profile.
