Study Notes
Bernoulli's Equation
- Bernoulli's equation describes the relationship between fluid speed, pressure, and elevation, stating that an increase in fluid speed occurs simultaneously with a decrease in pressure or a decrease in elevation.
Principle Behind Bernoulli's Equation
- Bernoulli's equation is a consequence of the principle of conservation of energy, which states that energy cannot be created or destroyed, only converted from one form to another.
Contributions of Daniel Bernoulli
- Daniel Bernoulli published his groundbreaking work "Hydrodynamica" in 1738, which laid the foundation for modern fluid dynamics.
Net Work Done on Fluid Segment
- The net work done on a segment of fluid depends on the change in kinetic energy, potential energy, and the work done by external forces.
Assumptions of Bernoulli's Equation
- Bernoulli's equation assumes that the density of the fluid is constant in streamline flow.
