Question

Derive dimensional formula of coefficient of viscosity

Answer 1

Answer:

Coefficient of viscosity (η)= Fr/Av

F= tangential Force, Area, r= distance between the layers, v= velocity. Kinematic viscosity is dynamic viscosity divided by density. So, its units would be . Its dimensional formula would be

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
