Question

1 Stoke is equal to:

• A. $10^{-4} \, \text{m}^2/\text{s}$
• B. $10^{-2} \, \text{m}^2/\text{s}$
• C. $10^{-3} \, \text{m}^2/\text{s}$
• D. $10^{-3} \, \text{m}^2/\text{h}$

Hint:

Remember: \[ 1 \, \text{Stoke} = 10^{-4} \, \text{m}^2/\text{s} \quad \text{and} \quad 1 \, \text{m}^2/\text{s} = 10^4 \, \text{Stokes}. \]

Answer 1

The Correct Option is A

1 Stoke is a unit of kinematic viscosity, commonly used in fluid mechanics. It is defined as: \[ 1 \, \text{St} = 10^{-4} \, \text{m}^2/\text{s}. \] This unit is based on the centimeter-gram-second (CGS) system.
