Q40

A centrifugal compressor works on the principle of

A.
Conversion of pressure energy into kinetic energy
B.
Conversion of kinetic energy into pressure energy
Answer
C.
Centripetal action
D.
Generating pressure directly

Answer: Option B

Solution

Answer: Option B
Solution:
So, in a compressor, first additional kinetic energy is imparted to the fluid with the help of a rotating impeller. ... So like this, pressure of a fluid is increased in a centrifugal compressor. So basically it works on the principle of conversation of kinetic energy into pressure energy.
