In multistage centrifugal compressors, what is true about each stage?

In multistage centrifugal compressors, each stage is designed to handle increasingly pressurized air or gas, which means that as you progress through the stages, the volume of gas decreases. This decrease in volume is a result of the compression process, where each stage compresses the gas further, leading to a higher density of the gas and a reduced volume in each subsequent stage.

The design of such compressors focuses on efficiency and performance, allowing the machine to achieve high pressures by utilizing several stages. Each stage contributes to the overall compression ratio, and the reduction in volume is a critical aspect that aids in achieving the desired output pressure.

Thus, in multistage centrifugal compressors, it is accurate to state that each stage has a smaller volume compared to the previous stage, resulting in an effective and incremental compression of the gas being processed.
