FLUID MECHANICS-WATER HAMMER The length of a 20cm rigid pipe carrying 0.15m3/s of water at 10oC is estimated by instantaneously closing a valve at the downstream end and noting the time required for the pressure fluctuation to complete a cycle. If the time required is 3 seconds, what is the length of the pipe?
