Question

Multistage compressors are used in industry because they:

• A. \(\text{reduce the cost of compressor}\)
• B. \(\text{reduce the size requirement}\)
• C. \(\text{resemble closely to isothermal compression}\)
• D. \(\text{are easy to control}\)

Hint:

Multistage compressors are preferred because they reduce work done, improve efficiency, and resemble isothermal compression.

Answer 1

The Correct Option is C

Step 1: Understanding multistage compression.
- Multistage compressors are used to compress gases in stages, cooling between each stage.
- This makes the process more efficient and thermally controlled, resembling isothermal compression.
Step 2: Explanation of incorrect options.
- Reduce cost (A): Multistage compressors are expensive due to complexity.
- Reduce size (B): They often require more space due to additional components.
- Easy to control (D): Control is more complex due to multiple stages.
Step 3: Selecting the correct option. Since multistage compression helps achieve a process closer to isothermal conditions, the correct answer is (C) resemble closely to isothermal compression.
