The advantage of multistage compression over single stage compression is

A Lower power consumption per unit of air delivered
B Higher volumetric efficiency
C Decreased discharge temperature
D All of the above

Correct Answer: All of the above

Advantages of multi-stage compressor over single stage compressor. -The fluid can be compressed to very high pressure.- The intercooler is more efficient than the cylinder wall cooling in a single stage compressor. -Pressure ratio per each stage is lowered and it reduces the leakage loss.
