What is the concept of fluid?

fluid, any liquid or gas or generally any material that cannot sustain a tangential, or shearing, force when at rest and that undergoes a continuous change in shape when subjected to such a stress.

What are the basic components of a fluid element in motion?

For example, to start with, the fluid element will have a general motion. General motion is made up of individual components. These components are, translation, linear deformation, rotation, or angular deformation. In addition, all of these components will be related to a time change ”δt”.

What are fluids Class 9?

Fluids : Fluids are the substances which have tendency to flow. A liquid is a fluid form of matter which occupies the space of the container.

What is deformation of fluid element?

So to describe the motion of the fluid element, in addition to Translation, we have to consider Rotation, Angular deformation, and Volumetric deformation. Angular deformation involves a distortion of the element in which planes of the element that were originally perpendicular are no longer perpendicular.

What is fluid nature?

The degree of fluidity of the membrane is determined by the lipid content of the membrane. The fluid nature of the membrane indicates function of cell growth, division and endocytosis. The plasma membrane regulates the entry and exit of the cell. Many molecules cross the cell membrane by diffusion and osmosis.

What is fluid give example?

Substances that can flow are called fluids. e.g. gases (oxygen, hydrogen). liquids (water, petrol. sulphuric acid).

What is fluid friction Class 8?

There is a friction whenever an object moves through a fluid.It is called fluid friction. When an object moves through water, it pushes the water out of the way and the water pushes back on the object. This push of water on the moving object creates fiction which tends to slow down the moving object.
