Why does water make that woosh noise flowing through pipes even though it’s not “hitting” anything?

I don’t mean banging or any unusual noises, I’m just talking about the usual noise of flowing water. What about the process of water flowing through pipes actually causes that sound? Raindrops make a sound because they’re hitting the ground, but water flowing through a pipe isn’t hitting anything…is it?

Answer: It is hitting the sides of the pipe. There is a friction between the water and the interior surfaces of the pipe.
