We can sort fluids into a few main groups based on how they act:
Newtonian Fluids: These fluids have a steady thickness, or viscosity. This means they flow in a predictable way, no matter the conditions. Examples of Newtonian fluids include water and air.
Non-Newtonian Fluids: The viscosity of these fluids changes depending on how much they are stirred or pushed. For instance, ketchup and paint can get thicker or thinner when they’re squeezed or stirred in different ways.
Compressible vs. Incompressible Fluids: Compressible fluids can change their density when pressure is added, like gases. On the other hand, incompressible fluids keep the same density, which is what most liquids do.
Knowing these different types of fluids helps us understand how they will act in different situations. This is really important when studying fluid mechanics!
