Improves volumetric efficiency for the given pressure ratio

Reduced work done per kg of air

Gives more uniform torque

All of these

There is no pressure drop in the intercooler

The compression in both the cylinders is polytropic

The suction and delivery of air takes place at constant pressure

All of the above

The compression ratio in each stage should be same

The intercooling should be perfect

The work done in each stage should be same

All of the above

Electric motor

Engine

Either (A) or (B)

None of the above

Roots blower compressor

Centrifugal blower compressor

Axial flow compressor

Both (B) and (C)
