水击与调压井实验台
Students should see both the sharp hammer wave and how a surge tank turns it into slow oscillation. Two 30 m test lines, 22 mm copper and 25 mm PVC, show the effect of pipe material on wave speed. A 1.5 m clear surge tank can be isolated, and four 0–2.5 MPa transducers log at 20 kHz from a 3 m constant head supply.
