Examples of Non-Newtonian Fluids

Non-Newtonian fluids are those whose viscosity changes under stress or strain, unlike Newtonian fluids, which maintain a constant viscosity regardless of the applied stress. In the choices provided, we can analyze each one:

1. Gasoline: A Newtonian fluid. Its viscosity remains constant regardless of the stress applied.

2. Air: Also considered a Newtonian fluid. The viscosity of air does not change with changes in flow conditions.

3. Liquid Plastic: This can be a non-Newtonian fluid depending on the type of plastic and its formulation. Some liquid plastics exhibit behaviors typical of non-Newtonian fluids, such as shear-thinning (decreasing viscosity under stress).

4. Blood: A complex fluid that behaves as a non-Newtonian fluid. The viscosity of blood changes based on the shear rate, making it a good example of a non-Newtonian fluid.

Summary of Findings

• Non-Newtonian Fluids: Liquid plastic, Blood
• Newtonian Fluids: Gasoline, Air

Final Answer

Recognize the following non-Newtonian fluids from the options: Liquid plastic and Blood.
