  • Chapter 5: Physics for Aviation › Aircraft Theory of Flight › Bernoulli’s Principle and Subsonic Flow

    Bernoulli’s Principle and Subsonic Flow The basic concept of subsonic airflow and the resulting pressure differentials was discovered by Daniel Bernoulli, a Swiss physicist. Bernoulli’s principle, as we refer to it today, states that “as the velocity ... that fluid will decrease, provided there is no energy added or energy taken away.” A direct application of Bernoulli’s principle is the study of air as it flows through either a converging or a diverging passage, and to relate…

    which is under a higher pressure, flows into the lower pressure venturi area and mixes with the air. Bernoulli’s principle is extremely important in understanding how some of the systems used in aviation work, including how the wing ... greater than the pressure on the top, and this pressure difference creates the lift on the wing. Bernoulli’s principle and the concept of lift on a wing are covered in greater depth in “Aircraft Theory of Flight” located…

    based calculations, we can conclude that the hydraulic system in question has a mechanical advantage of 20. Bernoulli’s Principle Bernoulli’s principle was originally stated to explain the action of a liquid flowing through the varying cross-sectional areas…
