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

The Stoke (St) serves as a unit for kinematic viscosity, frequently employed in fluid mechanics. Its definition is: \[ 1 \, \text{St} = 10^{-4} \, \text{m}^2/\text{s}. \] This unit finds its origin in the centimeter-gram-second (CGS) system.
