hello friends in this video we will see
the definition of kinematic viscosity
and it's unit so let us start with it
kinematic viscosity it is defined as the
ratio of dynamic viscosity to the
density or here if I write density it is
mass density of a fluid so kinematic 
viscosity it is defined as a ratio of
dynamic viscosity to the density of
fluid so mathematically kinematic
viscosity it is denoted by Greek letter
Mu and this is given by mass density or
simply density which is Rho it is
dynamic viscosity to density so here I
have this as dynamic viscosity that is
mu upon density so therefore mu it will
be equal to MU upon density so here I am
also saying the relation between kind of
kinetic viscosity and dynamic viscosity
next
here it's unit is it is meter square per
second and sometimes kinematic viscosity
is given in the form of Stokes
so one Stoke is equal to 10 raised to
minus 4 meter square per second so if in
the question they have given kinematic
viscosity in the form of Stoke that we
can convert it into meter square per
second and use it means we have to
converge stoke into meter square per second
by multiplying it by 10 raised to minus
4 so here in this video we have seen
kinematic viscosity with its relation
and its unit
