The kinematic viscosity (in stoke) and the absolute/dynamic viscosity (in poise) are the same for ______________ at room temperature ?
Correct answer: C. Water
- A. Air
- B. Mercury
- C. Water
- D. Alcohol
Explanation
Kinematic viscosity is ν = μ/ρ; in cgs units, it is numerically equal to dynamic viscosity when the density is 1 g/cm³. Water has approximately this density at room temperature, so its values in stokes and poise are nearly the same.
