Lack of control of the environment is often pinpointed as a cause of frustration and stress in confined animals. When the animal cannot control things, such as the feeding time or the lighting program, and when it cannot escape from things it finds unpleasant, it often behaves in a manner that indicates frustration.
Cavitation can also cause excessive pump vibration, which could damage pump bearings, wearing rings, and seals. A small number of centrifugal pumps are designed to operate under conditions where cavitation is unavoidable.
In fact, the force can be great enough to break the back of the elbow. Steam flowing in a system at 10,000 feet per minute is traveling more than 100 miles per hour. The slug of condensate is carried along by the steam flow. The second type of water hammer is actually cavitation. This is caused by a steam bubble forming or being pushed into a pipe completely filled with water. As the trapped steam bubble looses its latent heat, the bubble implodes, the wall of water comes back together and the force created can be severe.
