Flow of Fluids: Introduction

• Flow of fluids is the movement of a fluid (liquid or gas) from one location to another. It can be characterized based on various parameters such as velocity, pressure, and the type of fluid.
• Understanding fluid flow is essential in numerous engineering applications, including hydraulics, aerodynamics, and process engineering.
• Flow of fluids refers to the movement of liquids and gases. It can be classified into:
  1. Laminar Flow: Smooth, orderly flow where fluid particles move in parallel layers.
  2. Turbulent Flow: Chaotic, irregular flow with mixing of fluid particles.
  3. Transitional Flow: Between laminar and turbulent, with characteristics of both.

Fluid Pressure Under Flow of Fluids

• Fluid pressure is the force exerted by a fluid per unit area. It’s a scalar quantity and acts equally in all directions.
  1. Static Pressure: The pressure exerted by a fluid at rest.
  2. Dynamic Pressure: The pressure due to fluid motion, related to the fluid’s kinetic energy.
  3. Total Pressure: The sum of static and dynamic pressures.
