The coefficient of viscosity of a liquid is defined as the viscous force per unit area of contact between two layers having a unit velocity gradient between them.

η = \frac{F}{A ( \frac{Δ V _{z}}{Δ Z} )}

The SI unit of coefficient of viscosity is

k g / m

-s.
Also,

1

poise

= \frac{1}{10} k g m^{- 1} s^{- 1}

Q. The unit of the coefficient of viscosity in $S I$ system is

$m / k g - s$

$m - s / k g^{2}$

$k g / m - s^{2}$

$k g / m - s$

Q. The unit of the coefficient of viscosity in SI system is

m/kg−s

m−s/kg2

kg/m−s2

kg/m−s

The coefficient of viscosity of a liquid is defined as the viscous force per unit area of contact between two layers having a unit velocity gradient between them. η=A(ΔZΔVz​​)F​ The SI unit of coefficient of viscosity is kg/m-s. Also, 1 poise =101​kgm−1s−1

Q. The unit of the coefficient of viscosity in $S I$ system is

$m / k g - s$

$m - s / k g^{2}$

$k g / m - s^{2}$

$k g / m - s$
