CBSE · Class 11 · Physics · Mechanical Properties of FluidsThe SI unit of coefficient of viscosity ($\neta$) is:
Step-by-Step Solution
The SI unit of coefficient of viscosity is Pascal-second ($\ntext{Pa}\cdot\text{s}$) or $\text{N}\cdot\text{s/m}^2$. Poise is the CGS unit ($1 \text{ Pa}\cdot\text{s} = 10 \text{ poise}$).
