Which of the following is a disadvantage of an axial flow compressor?

An axial flow compressor is known for its ability to efficiently compress air with a relatively small footprint, which contributes to its compact design and makes it lightweight for the amount of air it processes. However, one of the main disadvantages of axial flow compressors is their high weight and cost compared to other types of compressors, like centrifugal compressors.

This higher cost is mainly due to the complexity of the design and the quality of materials required to withstand the high speeds involved during operation. Axial flow compressors require precise manufacturing standards and often involve advanced technology for their construction, further increasing costs. The combination of intricate components and the materials used for durability and efficiency contributes to a heavier and more expensive system overall.

Thus, while axial flow compressors boast benefits in efficiency and compactness, the trade-offs in weight and cost can be significant disadvantages, particularly in applications where budget and weight savings are critical.
