What is Dimensional Formula of Dynamic Viscosity?

Posted in Dimensional Formulae | Email This Post Email This Post |

Dynamic viscosity can be defined as the tangential force per unit area required to slide one layer against other when two layers are maintained ad a unit distance.

Dynamic viscosity = Stress ( Length / velocity).

Dimensional Formula of Stress= M1L-1T-2
Dimensional Formula of Length =M0L1T0
Dimensional Formula of velocity = M0L1T-1

Putting these values in above equation we get,

Dynamic viscosity = M1L-1T-2 ( T1)
Dynamic viscosity =M1L-1T-1

Dimensional Formula of Dynamic viscosity = M1L-1T-1
SI unit of Dynamic viscosity is Kg / ms
