  • si unit is N-s/m2 or pa.s & cgs unit is poise, 1 poise= .1 pa.s

  • As per Newton’s law of Viscosity:br /τ = μ * (du/dy)br /where, τ is the shear force ( Newton per meter^2 i.e. N/m^2 ) ; du/dy is the velocity gradient ( u is the velocity (m/s) and y is the thickness of the fluid layer (m) which gives the unit of velcity gradient as per second i.e. /s ) and μ is the coefficient of Viscosity.br /∴ μ = τ / (du/dy) i.e. N/ (m^2/s)br /Thus, the S.I. units of coefficient of viscosity are: strongN.s/m^2/strong
