Mechanical Engineering : Compressors, Gas Dynamics and Gas Turbines - Quiz(MCQ)

The compressor capacity is the ratio of workdone per cycle to the stroke volume.

The compression ratio for the compressor is always greater than unity.

During isothermal compression of air, the workdone in a compressor is maximum.

The ratio of the discharge pressure to the inlet pressure of air is called compressor efficiency.
