Hello, I am reading a book about simulation, modeling and automatic control. In a chapter about hydraulic transmission line, a pipe's "bandwidth" is mentioned. Contex: "Long pipes are used in large hydraulic installations where pipes of length up to 10 m are not uncommon. Moreover, in offshore oil and gas production pipes of several hundred meters may be used. A propagation time of T = 10ms will result if L = 10m. This introduces a time delay that may be significant if bandwidths up to 100 rad/s are required" I am used to bandwidth in the context of data transfer, but not in fluid mechanics. Can someone be so kind to explain the matter to me?
