Daniel Bernoulli discovered Bernoulli's principle in the 18th century while studying water flow through containers. Bernoulli's principle states that as the velocity of a fluid increases, the pressure within the fluid decreases. Some applications of Bernoulli's principle include venturi tubes, perfume sprayers, pitot tubes, the curved path of spinning balls, and the lift force created by airplane wings. The presentation provided examples of how Bernoulli's principle explains these phenomena in fluids and discussed its importance.
Bernoulli's Principle and its applications

- 2. The History of Bernoulli’s Principle Daniel Bernoulli (1700-1782) The Swiss mathematician and physicist discovered the Bernoulli's principle. He found the concept of Bernoulli’s principle when doing the experiment of water flow through the container. 2
- 3. Bernoulli’s Equation Where p is the pressure, ρ is the density, v is the velocity, h is elevation, and g is gravitational acceleration “Bernoulli's theorem states that in a steady, ideal flow of an incompressible fluid, the total energy at any point of the fluid is constant” . 3
- 4. Velocity of fluid at a narrow passage is faster than at a broad passage. As the velocity increases, the pressure decreases (Bernoulli’s Principle) Explanation 4
- 6. Venturi Tube A2 < A1 ; V2 >V1 According to Bernoulli’s Law, pressure at A2 is lower. 6
- 7. Using Bernoulli’s principle, we find that the speed of fluid coming from a spigot on an open tank is: This is called Torricelli’s theorem. Determining the velocity and debit of water spray in perforated tank 7
