Question

Newtonian fluid is defined as the fluid which
O
Obeys Hook's law
O is compressible
O
Obeys Newton's law of viscosity
O
Is incompressible
TI​

Answer 1

Answer:

Newton's law of viscosity

Explanation:

Newtonian fluids obey Newton’s law of viscosity. The viscosity is independent of the shear rate. Hence option (c) or the third one

Answer 2

Answer:

Obeys Newton's Law of Viscosity

Viscosity :

Viscosity is defined as the resistance between two adjacent layer of any fluid.

Newton's law of viscosity : it is stated that the viscous shear stress is directly proportional to the rate of shear strain or deformation or rate of angular deformation.

Shear stress between two adjacent layers of liquid also directly proportional to velocity gradient.

Newtonian fluids :

All type of fluids which obeys Newton's law of viscosity are called as newtonian fluids.

Examples of Newtonian fluids are water, kerosene, petrol, diesel, air etc.
