Hydrostatics Definition and Laws

Hydrostatics Definition
The Branch of science which deals with the study of fluids at rest.
Pascal’s Law
It states that the pressure or intensity of pressure at a point in a fluid at rest is equal in all directions.
Let consider a fluid at rest in a closed container then a change in pressure at one point will be transmitted without loss to every point of the fluid and to the walls of the container.

Surface Tension & Capillary Action

Surface Tension
Surface tension occurs at the interface of the liquid and a gas or at the interface of two liquids.
Surface tension (σ) is inversely proportional to temperature.
It acts when fluid is at rest.
It is a surface phenomenon.

Non-Newtonian Fluids

Types of Fluid
Newtonian Fluid
Non-Newtonian Fluid
Non- Newtonian Fluids
These types of fluids do not obey Newton’s Law of viscosity. The relation between Shear Stress and Velocity gradient is given by the following formula-

Vortex Motion Definition

Vortex Motion
A whirling or rotating mass of fluid is called vortex flow.
The flow of the fluid in a curved path.
Free Vortex Flow
In this flow fluid mass rotates due to the conservation of angular momentum. The velocity profile is inversely proportional to the radius.

Solid Friction and Viscosity Similarities & Dissimilarities

What is Friction?
Friction is the force that opposes the motion. It acts between the surfaces in contact.
There are basically four types of frictions-
Definition of Solid Friction
The friction that acts between the surfaces of solid surfaces. Static, Sliding and Rolling Frictions are the examples of Solid Frictions.
