radial flow compressor
axial flow compressor
roots blower
reciprocating compress
✅ The correct answer is option A.
Compressors
The multi-stage compression ofair as compared to single stage compression
improves volumetric efficiency for the given pressure ratio
reduces workdone per kg of air
gives more uniform torque
all of these
