   What is coefficient of viscosity?

   • A is 1cm2 and dv is 1cm/ s Then, The coefficient of viscosity is defined as the force of friction that is required to maintain a difference of velocity of 1cm/s between parallel layers of fluid. The unit is usually expressed in poise or centipoise.

   What is the SI unit of viscosity?

   • The SI unit of η is Newton-second per square meter (Ns. m-2) or Pascal-seconds (Pa .s) Hence the coefficient of viscosity is a measure of the resistance of the fluid to deformation at a given rate due to internal friction. The centimetre-gram-second or CGS unit of coefficient of viscosity,  η is dyne-sec/ cm2 which is equal to Poise.

   How do you calculate fluid viscosity?

   • F = ηvA /L …………………. (1), which gives us a working definition of fluid viscosity η. Solving for η, which is called the coefficient of viscosity or simply the viscosity, gives η= (FL)/ (vA) ……………………… (2) which defines viscosity in terms of how it is measured. The SI unit of viscosity is N ⋅ m/ [ (m/s)m^2 ] = (N/m^2)s or Pa ⋅ s.

   What is the dimensional formula for coefficient of viscosity?

   • The dimensional formula of Coefficient of Viscosity is given by, M1 L-1 T-1 Where, Coefficient of viscosity (η) = F × r × [A × v] -1 . . . . . (1) Where F = tangential force, r = distance between layers, A = Area, and v = velocity Since, Tangential Force (F) = Mass × Acceleration = M × [L T -2 ]
