s. The viscosity of a fluid is to be measured by this
viscometer. It’s constructed of two 40 cm long concentric
cylinders. The outer diameter of the inner cylinder is 12 cm, and
the gap between the two cylinders is 0.15 cm. The obtained readings
are below:

b) Determine variation of viscosity with temperature from the
experiment data for the motor lubricant.
c) Using newton’s law identify if this fluid is
Newtonian/Non-Newtonian and explain its characteristics. (From (b)
use dynamic viscosity value at 23˚C)
d) Illustrate the differences between the calculated
viscosity-temperature variation above with reference to the
standard dataset graph below.
