Fluid Dynamics: Key Concepts and Principles
Fluid Energy
- Kinetic Energy
- Potential Energy
- Internal Energy
Kinematic Viscosity
Dynamic Viscosity/Density
Streamlines
Tangent to flow velocity. Velocity potential is zero when the flow is irrotational or vorticity is “0”.
Bernoulli’s Equation is Applicable When
- Along a Streamline
- Inviscid
- Steady
- Incompressible
- No work is done
- No heat transfer
Bernoulli Equation was Developed by
Daniel Bernoulli and Leonhard Euler
Apply Shear Stress
- Solids: Will stop deforming
- Fluids: Continuously deform

Landscapes
A Landscape is Everything We Can See in an Area.
There Are Different Types of Landscape:
- Natural Landscapes: Natural features. They form very slowly over millions of years.
- Man-made Landscapes: Humans have changed the environment.
Types of Natural Landscapes: Inland (Away from the Sea) and Coastal (Near the Sea)
Landforms in Natural Inland Landscapes
- Mountains: Large inclines of rocky land that rise from the ground.
Parts of a Mountain: Summit, Foot, and Slope

Solving Equations
21: Adding the two equations and dividing by 10, we get: x + y = 10. Subtracting the two equations and dividing by -2, we get: x – y = 1. Solving these two new equations, we get, x = 11/2.
Geometry and Circles
30: Let ABCD be the rhombus circumscribing the circle with center O, such that AB, BC, CD, and DA touch the circle at points P, Q, R, and S respectively. We know that the tangents drawn to a circle from an exterior point are equal in length.
