Which of the following is a dimensionless parameter ?
Correct answer: A. None of these
- A. None of these
- B. Specific weight
- C. Kinematic viscosity
- D. Angular velocity
Explanation
Angular velocity has units of inverse time, specific weight has force per volume, and kinematic viscosity has area per time, so none is dimensionless. Hence the dimensionless choice is “None of these.”
