Answer:
If the shearing stress is linearly related to shearing strain then the fluid is called as Newtonian fluid.
Step-by-step explanation:
The other types of fluids are:
1) Non-Newtonian fluids which are further classified as
a) Thixotropic Fluid: Viscosity decreases with shearing stress over time.
b) Rehopactic Fluid: Viscosity increases with shearing stress over time.
c) Dilatant Fluid: Apparent viscosity increases with increase in stress.
d) Pseudoplastic: Apparent viscosity decreases with increase in stress.
