Question

what the ratio of s i unit to the CGS unit of coefficient of viscosity

Answer 1

Coefficient of viscosity has the SI unit Kg m^-1 s^-1
Cgs unit is g cm^-1 s^-1
So the ratio of the two is equal to
$\frac{1}{10}$
Hope this helps!!

Answer 2

Answer:  The ratio of SI and CGS unit of coefficient of viscosity  is 10:1.

Explanation:

We know that,

The coefficient of viscosity is defined as:

$\eta = \dfrac{Fr}{Av}$

Where,

F = tangential Force

A = Area

V = velocity

r = distance between the layers

SI unit of coefficient of viscosity is kg/m/s and CGS unit is poise.

The ratio of SI and CGS unit of coefficient of viscosity

$\dfrac{SI\ unit}{CGS\ unit}=\dfrac{kg\ m^{-1}s^{-1}}{0.1\ kg\ m^{-1}s^{-1}}$

$\dfrac{SI\ unit}{CGS\ unit}=\dfrac{10}{1}$

Hence, The ratio of SI and CGS unit of coefficient of viscosity  is 10:1.
