Correct answer: A. Means discarding a small fraction of circulating water to prevent and limit the concentration
- A. Means discarding a small fraction of circulating water to prevent and limit the concentration
- B. of salt and impurities
- C. Increases the scale forming tendencies of water
- D. Is undesirable
- E. All A., B. & C.
Explanation
Blowdown is the controlled discharge of a small portion of circulating cooling water to remove concentrated salts and impurities. This limits scaling and corrosion rather than increasing them.
