Q5 of 13 Page 35

What is the dimensional formula for the coefficient of viscosity?

Coefficient of Viscosity is the tangential force required to maintain a unit velocity gradient between two parallel layers of liquid of unit area and of unit distance.


Now, we know that,




Now, let [Mass] = M, [Distance] = L and [Time] = T


Then, …..1





(Since)


So,



Hence dimensional formula of Coefficient of Viscosity is .
