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).

Chkdsk performs a couple of functions, depending on how itâs run: 1  Chkdskâs basic function is to scan the integrity of the file system and file system metadata on a disk volume and fix any logical file system errors that it finds. 2  Chkdsk can also optionally scan every sector on a disk volume looking for bad sectors. Bad sectors come in two forms: soft bad sectors, that can occur when data is written badly, and hard bad sectors that can occur because of physical damage to the disk.
