Multistage compression of air as compared to single stage compression offers the advantage of______________?
Correct answer: D. All A , B. & C.
- A. Power saving per unit weight of air delivered
- B. Moisture elimination in the inter-stage cooler
- C. Increased volumetric efficiency
- D. All A , B. & C.
Explanation
Intercooling in multistage compression reduces the work required, condenses moisture between stages, and increases volumetric efficiency by lowering the inlet temperature of later stages. Thus all three stated benefits apply.
