Shape Factor Definition
A1F1-2 = A2F2-1
It indicates that the net radiant interchange may be evaluated by computing a one-way configuration factor from either surface to the other.

The Branch of science which deals with the study of fluids at rest.
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.
Dimensional Analysis Definition
All engineering quantities can be defined in four basic or fundamental dimensions- Mass (M), Length (L), Time (T), and Temperature (θ).
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.
Types of 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-
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.
