Chapter 1 – Problem 1.25

1.25 If 10 identical pipes (of the same material, diameter, thickness, etc.) join at a junction node, and a pressure wave of magnitude 50m approaches the junction node from one of the pipes, what is the magnitude and sign of the reflected pressure wave?

Solution:

T = (2/F) / (10/F) = 0.2

R = T – 1 = -0.8

R∆H = -40m.
