Capacity & power requirement for an air compressor working at high altitude compared to sea-level will be_______________?
Correct answer: B. Less
- A. More
- B. Less
- C. Same
- D. Either more or less; depends on the climatic conditions
Explanation
At high altitude, atmospheric pressure and air density are lower, so a compressor handles less mass of air for the same displacement and generally requires less power. Its volumetric capacity may be similar, but its mass capacity decreases.
