Fluid Mechanics

17.

Pick out the wrong statement about cavitation.

Sudden reduction of pressure in a fluid flow system caused by flow separation, vortex formation or abrupt closing of valve leads to cavitation.

Cavitation may be caused due to boiling of liquid by decreasing the pressure resulting in formation & collapse of vapor cavities.

Cavitation begins at higher static pressure and lower velocity in larger diameter pipelines resulting in audible noise.

Large scale cavitation can not damage pipeline, restrict fluid flow and damage steam turbine blades.
