Chapter 1 – Problem 1.26
1.26 If 100 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?
T = (2/F) / (100/F) = 0.02
A pipe (with incoming pressure wave) connected to 99 other identical pipes essentially amounts to a pipe connected to a fixed head reservoir boundary where the reflection coefficient = -1.0.
