Multistage compressors are used in industry, because they____________________?
Correct answer: B. Resemble closely to isothermal compression
- A. Reduce the cost of compressor
- B. Resemble closely to isothermal compression
- C. Reduce the size requirement
- D. Are easy to control
Explanation
Interstage cooling lowers the gas temperature and reduces the work required, so multistage compression approaches isothermal compression more closely than single-stage compression. Its main benefit is reduced power and discharge temperature, not simply lower equipment cost.
