n the agitators, the power required will be changed with the increase of diameter of agitator D. as ____________________?
Correct answer: D. D5
- A. IA. D2
- B. D9
- C. D
- D. D5
Explanation
For geometrically similar agitators operating at the same speed and fluid conditions, power varies approximately as the fifth power of impeller diameter, P ∝ D⁵. Thus even a modest increase in diameter greatly increases power demand.
