*Bernoulli's Principle* - *Definition*: The principle that states an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy. - *Key Points*: - *Conservation of Energy*: The total energy of a fluid remains constant. - *Pressure- Velocity Relationship*: As velocity increases, pressure decreases. - *Applications*: - *Aerodynamics*: Lift on airplane wings, airflow around objects. - *Fluid Dynamics*: Flow through pipes, nozzles, and venturi tubes. - *HV
