Diagram Poiseuille law showing pressure decrease along a horizontal pipe due to viscous head loss in laminar flow (p1 > p2 > p3)

3. Law of Poiseuille: Viscous Flow in Pipes

  • CEZ 

Poiseuille’s law explains why pressure continuously decreases in laminar pipe flow due to viscous energy dissipation, even in pipes with constant diameter and steady velocity.

2. Bernoulli’s Principle: Equation&Applications

  • CEZ 

Bernoulli’s Principle Explained for Engineers In the article Fluid Dynamics Basics for Engineers we introduced the concepts of streamlines, flow tubes, and the continuity equation, showing how velocity is inversely proportional to the cross-sectional area of a pipe. This leads naturally to the next fundamental concept: the relationship between pressure, velocity, and elevation described by Bernoulli’s… Read More »2. Bernoulli’s Principle: Equation&Applications

1. Fluid Dynamics Basics for Engineers

  • CEZ 

Fluid Dynamics Basics for Engineers Fluid dynamics is one of the fundamental sciences in chemical and process engineering, just like thermodynamics and heat transfer. It is not itself a unit operation, but rather the theoretical foundation that allows us to design pumps, pipelines, valves, and entire networks of fluid transport. When these principles are applied in… Read More »1. Fluid Dynamics Basics for Engineers
