Speed of industrial paddle agitator ranges from _____________ rpm?
Correct answer: B. 20 to 100
- A. 1 to 5
- B. 20 to 100
- C. 500 to 750
- D. 1000 to 2000
Explanation
Paddle agitators are large, slow-speed impellers used mainly for blending and gentle mixing, typically operating around 20 to 100 rpm. The higher ranges listed are characteristic of smaller, high-speed impellers.
