- For a completed water-hammer analysis, explain how the plane would look.
- A hot-water line 50 ft long and ~ in. in diameter is made of cast iron. The water is at 150°F and is flowing at 5 ft/s when the valve is suddenly cut off.
(a) At what speed will the resulting wave propagate?
(b) How long will it take the wave to reach the other end of the pipe?
(c) What might be the frequency of the resulting vibration?
(d) What does this say about the noise you hear in a house when a faucet is abruptly shut off?
