Viscosity mu is expressed as a proportionality constant betw

Viscosity, mu, is expressed as a proportionality constant between sheer stress, tau, and gradient of speed, tau = mu times (du/dy). What are the units of mu in terms of kg, m and s? kg/ms kg/m^2s kg/m kg/m^2s^2 kg/m^2

Solution

Solution:

The correct option is A . kg/ms

This can be derived by using the MKS system of units for each of the terms in given equation and equating them as shown.
