Conceptual Question Involving Fluids

In summary, the conversation discusses the different outcomes when placing a sphere with a density less than water in two different cylinders - one with a spinning column of water and the other with a still column. The speaker suggests that the sphere takes longer to float to the top in the spinning column due to Coriolis acceleration, which is further explained through a Google search provided.

A sphere (with density less than that of water) is placed into 2 different cylinders. One with a spinning column of water and the other with a still column of water. Why does the sphere in the spinning column of water take much longer to float to the top of the cylinder?

I was thinking about the sphere taking a larger trajectory thus experiencing more retarding force from the spinning column of water but is there anything else that I am missing?

FAQ: Conceptual Question Involving Fluids

What is a fluid?

A fluid is a substance that can flow and take the shape of its container. It can be a liquid or a gas.

How does density affect the behavior of fluids?

Density is the mass per unit volume of a substance. In fluids, density determines how the fluid will behave under different conditions. A fluid with a higher density will sink in a fluid with a lower density. Density also affects the pressure and buoyancy of fluids.

What is the difference between a Newtonian and a non-Newtonian fluid?

A Newtonian fluid follows Newton's law of viscosity, which states that the shear stress is directly proportional to the rate of shear strain. This means that the viscosity of a Newtonian fluid remains constant regardless of the shear rate. On the other hand, a non-Newtonian fluid does not follow this law and its viscosity can change with the shear rate.

What is Bernoulli's principle and how does it apply to fluids?

Bernoulli's principle states that in a fluid flow, an increase in the speed of the fluid results in a decrease in pressure. This principle is based on the conservation of energy and is often used to explain the lift force on an airplane wing or the flow of fluids through pipes.

How does surface tension affect the behavior of fluids?

Surface tension is the attractive force between molecules at the surface of a fluid. It causes the surface of a liquid to behave like a thin elastic skin. Surface tension affects the shape of droplets, the movement of objects on the surface of a liquid, and can also be seen in capillary action, where a liquid flows against gravity in a narrow tube.
