A. Liquids
B. Gases
C. Mixture of hydrocarbons
D. None of these

A. Particle size
B. Fluid viscosity
C. Density of both the particle & the fluid
D. All A., B. and C.

A. U-tube water
B. U-tube mercury
C. Inclined tube mercury
D. Inclined tube water

A. Total pressure
B. Total energy
C. Velocity head
D. None of these

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 cannot damage pipeline, restrict fluid flow and damage steam turbine
blades
