What Is The Dimensions And Units Of Viscosity?

What Is The Dimensions And Units Of Viscosity? dimensions. The dimensions of dynamic viscosity are force × time ÷ area. The unit of viscosity, accordingly, is newton-second per square metre, which is usually expressed as pascal-second in SI units. What is the dimension of viscosity? Or, η = [M1 L1 T– 2] × [M0 L2
