Viscosity is a measure of a fluid's resistance to flow.

Pressure is defined as the force (F) applied perpendicular to the surface of an object per unit area (A) over which that force is distributed (P = F/A). In a fluid, pressure acts in all directions. 2. Pascal’s Law

Gases (like air) are compressible; liquids (like water) are mostly incompressible. Common Applications in Engineering Aerodynamics: Designing cars and airplanes to reduce drag.

Start with concept maps to visualize the big picture. Mind maps on platforms like EdrawMind show how fluid statics, fluid kinematics, and fluid dynamics relate to each other.
