Question

The dimensional formula of coefficient of viscosity is

Answer 1

Coefficient of viscosity = (force × distance) ÷ (area × velocity)

Therefore dimension of coefficient of viscosity is [ML^-1T^-1]

Unit is N/m2 or Pa s or decapoise

Answer 2

Answer:

Coefficient of viscosity = F × r × [A × v]⁻¹

η = F × r × [A × v]⁻¹

η = MLT⁻² × L × [L²× LT⁻¹]⁻¹

η = MLT⁻² × L × L⁻² × L⁻¹T

η = MLT⁻² × L⁻¹  × L⁻¹T

η = MLT⁻² × L⁻²T

η = ML⁻¹T⁻¹
