Study Notes
Bernoulli's Principle
- An increase in the speed of a fluid results in a decrease in its static pressure.
- This relationship illustrates the conservation of energy within a fluid system.
Derivation of Bernoulli's Equation
- Bernoulli's equation, expressed in its common form, was derived by Daniel Bernoulli.
Underlying Principle
- Bernoulli's principle can be derived from the conservation of mechanical energy principle, emphasizing energy transfer within fluid motion.
Energy Conservation in Fluids
- The total energy of a fluid, which includes kinetic energy, potential energy, and internal energy, remains constant throughout the fluid's flow.
- This concept signifies that energy can transform from one form to another but cannot be created or destroyed.
Energy Uniformity in Reservoirs
- Within a reservoir, the sum of all forms of energy for the fluid remains uniform, indicating equilibrium throughout the system.
