Answer:

The coefficient of viscosity is the tangential force per unit area required to maintain a unit velocity gradient.

In C.G.S ystem, the unit of coefficient of viscosity is dynes/cm

2

.

In MKS system, the unit of coefficient of viscosity is N.s/m

2

.

1 N= 10

5

dyne and 1m

2

=10

⇒

10

10

5

dynes/cm

=10

Thus, the ratio of

ηCGS

ηMKS

=10
