Question

Unit of viscosity is

• A. $$m/sec$$
• B. $$kg sec/m^2$$
• C. $$N sec/m^2$$
• D. $$Ns^2 /m$$

Answer 1

Answer:

$$N sec/m^2$$

Viscosity is the internal resistance of a fluid to motion. The unit of dynamic viscosity is $N. s / m ^ 2$ . Kinematic viscosity is the ratio of dynamic viscosity to density and its unit is Stoke or $m ^ 2 / s$
