does anyone know anything about the Bernoulli's effect/principles???

Bernoulli's Principle \nThis is an important principle involving the movement of a fluid through a pressure difference. Suppose a fluid is moving in a horizontal direction and encounters a pressure difference. This pressure difference will result in a net force, which by Newton's 2nd law will cause an acceleration of the fluid.  \n\nBernoulli's principle thus says that a rise (fall) in pressure in a flowing fluid must always be accompanied by a decrease (increase) in the speed, and conversely, if an increase (decrease) in , the speed of the fluid results in a decrease (increase) in the pressure. This is at the heart of a number of everyday phenomena. As a very trivial example, Bernouilli's principle is responsible for the fact that a shower curtain gets ``sucked inwards'' when the water is first turned on. What happens is that the increased water/air velocity inside the curtain (relative to the still air on the other side) causes a pressure drop. The pressure difference between the outside and inside causes a net force on the shower curtain which sucks it inward. A more useful example is provided by the functioning of a perfume bottle: squeezing the bulb over the fluid creates a low pressure area due to the higher speed of the air, which subsequently draws the fluid up.

Most of these principles are addressed in detail in physics text books.  Perhaps you might try at a local college or high school  library.

Way to go Arbitrage!  Oh to funny guy- yeah we get that E=MC2  IS a formula- but if you really want to "get it" Check out Maxwells equations. It's a great time to be a science nerd with all this info pouring in now! Figure it out & go up one on Albert!

Biot-Savart Law. Look it up.

Check the Michaelis-Menten equation.It's too long to write it all down for you ;)

Bernoulli's equation relates pressure to the speed of a moving fluid.  That's entirely different to what the question here is.\n\nThe reason things move from high pressure to low pressure is because such a pressure gradient is statistically unstable.  The principle is so simple it's studid.  Think of a fluid as being a bunch of tiny particles, flying around and banging into one another.  At high pressure, the particles are packed closely together, and they will hit eachother more frequently than they will at low pressure.  Every time two particles collide, they are driven away from one another.  So if a particle hits a particle and bounces toward a place of greater pressure, it will be statistically very likely to hit another particle again in a big hurry.  If it bounces to a place of lower pressure, it will be statistically less likely to hit another particle in a hurry.  If you sum up all of the collisions, the result is that movement up a pressure gradient is less stable--that is, it lasts a short time--than movement down a pressure gradient.  The effect of this is that on average, you end up with a net flux of particles in the direction down the pressure gradient.\n\nThis sounds absurd, but it ultimately makes the flow occur.  You have to realize that particles move very, very fast, and collisions happen with a frequency we can barely imagine.  So imagine you're an air molecule in a soda can that's been shaken.  There's so much pressure, that any way you go, you hit another molecule almost instantly.  Suddenly the top is opened.  Those molecule that are closest to the opnening are at an extreme point in the pressure gradient: below them are crowded molecules, and above them are the more rarified atmospheric air molecules.  They bump about at random.  But if they're bumped down into the can, they go little distance before being bounced back.  If they're bumped up, they go much further before hitting another molecule.  This means that in the vacinity of the opening, the pressure is reduced, and there are less molecules in that area.  Now the pressure gradient has propagated into the can.  Those areas adjacent to that area near the opnening now experience the same effect--being bumped away from the openeing meets it with a quick collision, while being bumped toward the opening makes it able to travel further before hitting another molecule, because so many have left the can that the area near the opening is much less crowded.  This keeps happeneing until the pressure inside and outside the can is the same, due to a net flux of molecules out of the can, and it happens really, really fast.\n\n\nConservation of momentum also makes it so that in an elastic collision, the net momentum of the collision before and after a collision is unchanged.  So for fluid in a pipe, that means most collisions will keep everything going down the pressure gradient.

It's called 'impulse' and any good, lower division, physics book will have an explanation of what it is and how it works.\n\n\nDoug

The Bernoulli effect does not help inverted flight, it hinders it. The Bernoulli "lift" is downwards when flying inverted. Actual upward lift is generated by Newtonian lift.\nAirplane wings use a combination of Bernoulli's principle (the faster air flows over a surface the lower its pressure) and "Reaction" or Newtonian lift, the force produced by the downward acceleration of an air mass by a plane surface that is tilted with respect to the velocity. (See references). The upper surface of the wing is curved and the lower surface is relatively straight. Thus air passing over the wing has farther to travel before it rejoins the air that went under the wing, and must move faster. The lower pressure over the wing creates a Bernoulli lift force. The wing also has a positive "angle of attack" (basically the tilt angle of the wing's lower surface) producing Newtonian lift. Ref. 1 estimates that airplanes have more Newtonian than Bernoullian lift. In normal flight the total lift is the sum of these two forces.\nInverted flight requires the difference, not the sum, of the two lift components to equal the plane's weight, in other words, a lot more Newtonian lift. This is achieved by increased angle of attack, flaps, etc. which also increase drag. That is why inverted flight takes more power.

I have used the Bernoulli equation to calculate pressure drop through piping and to size pumps (determine required head pressure).  You can't get much more real than that.

Bernoulli principle is only partially true for a airplane.\n \nThe main reason for airplane creating lift is when an airstream passes by something which deflects it downward. The force created by this deflection of the air creates an equal and opposite force upward on the wing according to Newton's third law of motion. The deflection of airflow downward during the creation of lift is known as downwash.\n\nA false explanation for lift is known as the "equal transit-time" explanation, it states that the parcels of air which are divided by an airfoil must rejoin again; because of the greater curvature (and hence longer path) of the upper surface of an aerofoil, the air going over the top must go faster in order to "catch up" with the air flowing around the bottom. Therefore, because of its higher speed the pressure of the air above the airfoil must be lower. Despite the fact that this "explanation" is probably the most common of all, it is false.

Same reason it makes it go up. Bernoulli's law.
