During agitation of liquids, power consumption during laminar flow is not proportional to the ________________?
Correct answer: A. Density of the liquid
- A. Density of the liquid
- B. Viscosity of the liquid
- C. Cube of impeller diameters
- D. Square of rotational speed
Explanation
For laminar agitation, power is proportional to viscosity, the square of rotational speed, and the cube of impeller diameter, but it is independent of liquid density. Density appears in the turbulent-flow power relation, which is the likely trap.
