Question: Which of the following is a characteristic of a non-Newtonian fluid?

Options:

Correct Answer: Viscosity changes with shear rate

Solution:

Non-Newtonian fluids exhibit a change in viscosity with varying shear rates, unlike Newtonian fluids which have a constant viscosity.

Which of the following is a characteristic of a non-Newtonian fluid?

Which of the following is a characteristic of a non-Newtonian fluid?

Step 1: Understand what a fluid is. A fluid is a substance that can flow, like water or oil.
Step 2: Learn about Newtonian fluids. These fluids have a constant viscosity, meaning their thickness does not change when you stir or apply force.
Step 3: Learn about non-Newtonian fluids. These fluids change their viscosity when you apply different amounts of force or shear.
Step 4: Recognize that non-Newtonian fluids can become thicker or thinner depending on how fast you stir them or how much force you apply.
Step 5: Identify examples of non-Newtonian fluids, such as ketchup or cornstarch mixed with water, which behave differently under different conditions.
