Other Cavitation

Home Evidence Physics Other Cavitation References	Cavitation occurs in the bottom of the bottles that we break, but it can also be found in many other places that have great impact on the engineering of different systems. Two other places where cavitation occurs includes: 1. pump systems 2. boat/ship propellers. 3. animals

Pumps typically have a very hard time dealing with cavitation. This is because on one side of the pump there is a much lower pressure. Bernoulli’s equation is used for in-depth analysis of the cavitation of pumps. A great site that I would like to reference is Hydrodynamics of Pumps. http://caltechbook.library.caltech.edu/22/1/chap5.htm,  One cannot just engineer a pump system without looking at the consequences that cavitation may bring about.	Most propellers are always cavitating while below the water because there is such low pressure on the front of the blade where a "void" of water is being produced from the pushing forward off of all the other water around. You can really see this by inspecting the picture above closely.	Just as cavitation works on other high-speed underwater apparatuses, animals can be affected by cavitation while swimming. In particular, the dolphin. Dolphins swim so fast that cavitation occurs on their fins and forces them to slow down to avoid the pain of the collapsing air pockets.
