Question

What type of fluid is alcohol?

(a) Thixotropy

(b) Rheopexy fluids

(c) Non- Newtonian fluid

(d) Newtonian fluid

This question was posed to me by my school teacher while I was bunking the class.

Question is from Fluid Flow Theory in division Fluid Flow Theory & Applications of Food Processing Unit Operations

Answer 1

Right option is (d) Newtonian fluid

For explanation I would say: Newtonian fluid depends on the Newton’s law of viscosity. The law states that shear stress between the neighboring fluid layers is directly proportional to velocity gradients between the two layers. Alcohol, water, air are some of the examples of Newtonian fluid.
