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).

Congestive heart failure (CHF) is a term used to describe the heartâs inability to pump enough blood to meet the bodyâs needs. Heart failure does not mean that the heart has failed completely, but rather that the heart is not strong enough to meet the bodyâs needs at times of stress or increased activity. The left ventricle normally receives blood from the lungs and pumps blood through the arteries to the brain, internal organs and extremities.
