Pick out the wrong statement about cavitation.

Question

Options:

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

Answer: Option D
