Bernoulli's Principle
- 1. FLUID MECHANICS Presentation Bernoulli’s Principle Umar Tariq Husnnain Javeed Adil Faraz Muhammad Zaroon
- 3. Bernoulli’s Principle Theory - Introduction Presented by Daniel Bernoulli in his book Hydrodynamica in 1738
- 4. Bernoulli’s Principle Theory - Statement Increase in the speed of the fluid occur simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. OR In a horizontal pipe, the highest fluid pressure is in the section where the flow speed is the lowest, and the lowest pressure is at the section where the flow speed is the biggest. APPLICABLE : INCOMPRESSIBLE - NON VISCOS - NON STEADY
- 5. Bernoulli’s Principle Theory - Explanation Figure Section of pipe shown above Bernoulli’s Equation can be written as
- 6. Bernoulli’s Principle Theory - Equation Where (in SI units) P= static pressure of fluid at the cross section ρ= density of the flowing fluid g= acceleration due to gravity; v= mean velocity of fluid flow at the cross section h= elevation head of the center of the cross section with respect to a datum.
