Bernoulli's Principle - Bernoulli On Pressure In Moving Fluid

Nature has established many codes in the Universe (perhaps infinitely many). Birds were able to decode a critical aspect of the flight code long before the emergence of humans. Then came Daniel Bernoulli, son of John Bernoulli (1667-1748), with the Bernoulli's Principle. John Bernoulli and his elder brother Jacob Bernoulli contributed greatly to mathematics. Daniel Bernoulli and his brother Nicholas Bernoulli also contributed greatly to mathematics.

(a) What is the Bernoulli's Principle?
(b) Can one relate the principle of suction to the Bernoulli's Principle?
(c) Isaac Newtons third law established the action -reaction relationship. Identify the action and the reaction in the Bernoulli's Principle.
(d) What other scenarios does one find the Bernoulli's Principle in action?

The strings: S7P3A32 (Force - Push).

The math:
Pj Problem of Interest is of type force (push). Pressure is force per unit area.

(a) The Bernoulli's Principle states that the pressure in a moving stream of fluid is less than the pressure in the surrounding fluid.

(b) The principle of suction is correctly explained as an evacuation scenario: air is removed from space, so pressure is decreased, so surrounding fluid moves in to equalize pressure. From the Bernoulli's Principle perspective, the suction can be explained as air stream in motion before complete evacuation.

(c) The action is the moving stream of fluid which creates a lower pressure region relative to the pressure in surrounding fluid. The reaction is the movement of fluid from the surrouding fluid at higher pressure (thrust) to the region of lower pressure in the moving stream.

(d) The Bernoulli's Principle is present wherever there is flight. It is also present in weather systems scenarios.
