The result may be heard as a loud bang, repetitive banging (as the shock wave travels back and forth in the plumbing system), or as some shuddering.o for a valve closing instantaneously, the maximum magnitude of the water hammer pulse is: where Î´ P is the magnitude of the pressure wave (Pa), Ï is the density of the fluid (kgm â3), a0 is the speed of sound in the fluid (ms â1), and Î´ v is the change in the fluid's velocity (ms â1).
