Question: What type of fluid exhibits a constant viscosity regardless of the shear rate?

Options:

Correct Answer: Newtonian fluid

Solution:

Newtonian fluids have a constant viscosity that does not change with the shear rate.

What type of fluid exhibits a constant viscosity regardless of the shear rate?

What type of fluid exhibits a constant viscosity regardless of the shear rate?

Step 1: Understand what viscosity means. Viscosity is a measure of a fluid's resistance to flow.
Step 2: Learn about shear rate. Shear rate is how fast layers of fluid move past each other.
Step 3: Identify the type of fluid that has a constant viscosity. This means its resistance to flow does not change, even if the shear rate changes.
Step 4: Recognize that Newtonian fluids are the type of fluids that maintain a constant viscosity regardless of the shear rate.
