What we have learnt
- Bernoulli's equation applies under specific conditions such as steady, incompressible, and frictionless flow.
- The concept of virtual fluid balls helps visualize the flow and understand energy relationships.
- Limitations of Bernoulli's equation include neglecting frictional effects near solid surfaces and in mixing zones.
Key Concepts
- -- Bernoulli's Equation
- A principle that establishes a relationship between the pressure, velocity, and height in fluid flow.
- -- Streamlines
- Imaginary lines that represent the flow of fluid, helping visualize the motion and forces in a fluid system.
- -- Virtual Fluid Balls
- A conceptual tool for understanding fluid dynamics by visualizing the motion of hypothetical balls representing fluid elements.
- -- Coefficient of Discharge (Cd)
- A dimensionless number used to characterize the discharge behavior of a fluid through an orifice, accounting for energy losses.
