13. Basics of fluid mechanics-II (contd.)
The chapter delves into the fundamentals of fluid dynamics, notably Bernoulli's equation, discussing its derivation and application along a streamline. It highlights the critical assumptions for using Bernoulli’s equation, such as frictionless and steady flow, and includes various applications like the stagnation tube and pitot tube. Moreover, it emphasizes the concepts of hydraulic grade line and energy grade line, laying a groundwork for understanding flow dynamics in civil engineering contexts.

What we have learnt
- Bernoulli's equation represents the conservation of mechanical energy in fluid flow.
- Key assumptions for applying Bernoulli's equation include frictionless flow, steady flow, and constant density.
- The hydraulic grade line (HGL) and energy grade line (EGL) are crucial for analyzing flow behavior in various systems.
Key Concepts
- -- Bernoulli's Equation
- An equation that expresses the principle of conservation of energy for flowing fluids, stating that the sum of pressure energy, potential energy, and kinetic energy per unit volume is constant along a streamline.
- -- Hydraulic Grade Line (HGL)
- A line that represents the total potential energy head (pressure head and elevation head) of the fluid in a system.
- -- Energy Grade Line (EGL)
- A line that shows the total mechanical energy head (including kinetic energy) of the fluid in a system.
