Turbine impeller____________________?
Correct answer: C. Is effective over wide range of viscosities
- A. Produces only radial current
- B. Produces only tangential current
- C. Is effective over wide range of viscosities
- D. Does not produce tangential current
Explanation
A turbine impeller can generate both radial and tangential circulation, so the options claiming only one type of current are false. Its main advantage among these choices is useful performance over a relatively wide viscosity range.
