A fluid at rest experiences no shear force. When in motion, though, shear 
forces can be set up due to viscosity and ‘turbulence’ which oppose motion, 
producing a ‘frictional’ effect. 
A fluid consists of a large number of individual particles moving in the general 
direction of flow but usually not parallel to each other. The path followed by a 
particle is called a path line. A pathline (or particle path) is the trajectory of an 
individual element of fluid.

Introduction to Water Hammer Phenomenon in Pipeline : Fluid Mechanics (mechanical engineering)

A sudden change of flow rate in a large pipeline (caused by valve closure, pump 
shutoff, etc.) may affect a large mass of water moving inside the pipe. 
The force resulting from changing the speed of the water mass could cause a 
pressure rise in the pipe with a magnitude several times greater than the normal 
static pressure in the pipe. 
This phenomenon is commonly known as the water hammer phenomenon. The 
excessive pressure may fracture the pipe walls or cause other damage to the 
pipeline ...
