EXPERIMENTAL
DETERMINATION OF VISCOSITY OF A HIGH VISCOUS LIQUID USING STOKES' METHOD
Let
us consider a tall jar in which a high viscous liquid such as castor oil is
filled as shown in Fig.2.4.
A
steel ball is dropped from the top of the Jar and the time taken for the ball
to travel from A to B, B to C, C to D etc is noted using a stop watch.
When
the time taken for the ball to move between the marking say B to C & C to D
(or) D to E is equal, then it implies that the ball has reached terminal
velocity.
∴ Terminal velocity v = Distance
travelled by the ball (x) / Time taken (t)
i.e., v = x / t ………….(1)
The
experiment is repeated for similar such balls of same radius and the mean value
of terminal velocity shall be calculated.
Now,
by finding the radius of the ball using screw guage and substituting the values
of density of the liquid (ρ') and
density of the ball (ρ) in the given
formula,
the
co‒efficient of viscosity of the high viscous liquid shall be determined.
Applications
(i)
Stokes' law/principle is used in understanding the phenomenon of settling of
particles in liquids.
(ii)
This method is used to find the viscocity of high viscous liquids.
(iii)
Stokes' law is used in various fields such as sedimentation, Aerosol science
etc.
(iv)
This principle is also used in fluid dynamics, parachute designing etc.
