Questions & Step-by-Step Solutions
Which of the following is a characteristic of a 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 viscosity. Viscosity is a measure of how thick or sticky a fluid is. It tells us how easily a fluid can flow.
Step 3: Know what shear rate means. Shear rate is how fast the fluid is being stirred or moved.
Step 4: Recognize the difference between Newtonian and non-Newtonian fluids. A Newtonian fluid has a constant viscosity, meaning it flows the same way no matter how fast you stir it.
Step 5: Conclude that a characteristic of a Newtonian fluid is that its viscosity does not change with different shear rates.
