Question
Obtain the dimensional formula for coefficient of viscosity.
✓
Answer
According to Stoke's law, viscous force $\text{F}=6\text{}\pi\eta\text{r}\upsilon$$\therefore$ Demensions of $\eta$ are $\frac{[\text{F}]}{\text{[r]}[\upsilon]}=\frac{\text{[M L T}^{-2}]}{[\text{L}]\times[\text{LT}^{-1}]}[\text{M}^1\text{L}^{-1}\text{T}^{-1}].$
