Are you focusing on (hydraulics) or gases (aerodynamics)?
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 fluid mechanics for dummies pdf
: Studying fluids at rest (e.g., pressure in a dam or buoyancy of a ship). Fluid Dynamics : Fluids in motion. Key equations include the Continuity Equation (mass conservation) and Bernoulli’s Equation (energy conservation). : The "thickness" of a fluid or its resistance to flow.
