Mechanical Engineering - Compressors, Gas Dynamics and Gas Turbines - Discussion

The correct Answer is option B.

I guess its answer is large quantities of air at high pressure.

A rotary screw compressor is a type of gas compressor that uses a rotary-type positive-displacement mechanism. They are commonly used to replace piston compressors where large volumes of high-pressure air are needed, either for large industrial applications or to operate high-power air tools such as jackhammers.
