### What is Shape Factor? Definition and Important Terms

0
Shape Factor Definition Reciprocity Theorem 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. Shape Factor of Some Important Surfaces

### Hydrostatics Definition and Laws

0
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.

### Dimensional Analysis and its Application Notes

0
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 & Capillary Action

0
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

2
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, Forced Vortex Free Vortex Flow, Differences

0
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.
