A.
Sudden reduction of pressure in a fluid flow system caused by flow separation, vortex formation or abrupt closing of valve leads to cavitation |
|
B.
Cavitation may be caused due to boiling of liquid by decreasing the pressure resulting in formation & collapse of vapor cavities |
|
C.
Cavitation begins at higher static pressure and lower velocity in larger diameter pipelines resulting in audible noise |
|
D.
Large scale cavitation can not damage pipeline, restrict fluid flow and damage steam turbine blades |
