22. Lecture No 11: Bernoulli Equation
The chapter focuses on the Bernoulli equation, an essential concept in fluid mechanics that relates fluid pressure, velocity, and potential energy. It explains the application of Bernoulli's principles in real-world scenarios such as blood flow and cyclonic winds, alongside experimental verification. The principles are derived and discussed in relation to mass conservation and momentum, illustrating the versatility and importance of the Bernoulli equation in various fields, especially civil and mechanical engineering.

What we have learnt
- The Bernoulli equation is fundamental for analyzing fluid flow problems using energy conservation principles.
- There exists an inverse relationship between pressure and velocity in fluids, illustrated by real-life examples like blood circulation and cyclonic winds.
- The verification of Bernoulli's principles in experimental setups demonstrates their practical applicability in engineering contexts.
Key Concepts
- -- Bernoulli's Equation
- A principle that states that in a flowing fluid, an increase in speed occurs simultaneously with a decrease in pressure or potential energy.
- -- Flow Energy
- The component of energy in a fluid system due to pressure, which helps in understanding the behavior of fluids in motion.
- -- Incompressible Flow
- A flow regime where the fluid density remains constant despite changes in pressure, typical in most liquids.
