A compressor at high altitudes will require ________ power.

Answer: Option C

At high altitudes, the air density decreases, which means that there is less oxygen available for combustion in engines and compressors.

To compensate for this reduction in air density, a compressor must work harder to intake and compress the air to achieve the desired pressure levels. As a result, the compressor will require more power to maintain its performance and efficiency under these conditions.

This increased power demand is necessary to overcome the challenges posed by the thinner atmosphere, ensuring that the system operates effectively even at elevated altitudes.
