- What is the cause and what is the effect in the Bernoulli effect?
The Bernoulli effect is very similar to the reasoning that when an object is at rest the normal force is equal to the weight If the normal force is greater than the weight the object will accelerate upward and when it smaller it will accelerate downward
- fluid dynamics - Whats wrong with this argument that aerodynamic lift . . .
Bernoulli effect still doesn't explain lift; it's just the beginning of it It's like saying soda gets sucked up your straw because you suck on the straw What actually happens is the lower pressure inside the straw allows normal atmospheric pressure to push the liquid up the straw
- Is Magnus effect a corollary of Bernoulli principle?
Magnus effect is commonly explained using Bernoulli principle However, taking the lift on a rotating cylinder as an example, the velocity difference is caused by the extra work done by the rotating cylinder but not by the pressure difference, the Bernoulli principle is basically energy conservation along a streamline
- How much effect does the Bernoulli effect have on lift?
20 I understand that the Bernoulli effect is a flawed explanation for the cause of lift, and does not cause much at all, but how much? Is there any experimental data on the force caused by the Bernoulli effect? Maybe implicitly through data of the pressure difference between the top and underside of an aeroplane's wings
- fluid dynamics - Are eductors working on the Bernoulli principle . . .
The Bernoulli effect from the flow of pumped water causes suction at the mouth of the dredge Water and sediment are sucked from the excavation site and released from the far end of the tube" This time water air steam etc (usually water) at more velocity attracts water, create suction, lift water and then debris along with it @Jokela Wiki
- What really allows airplanes to fly? - Physics Stack Exchange
What aerodynamic effects actually contribute to producing the lift on an airplane? I know there's a common belief that lift comes from the Bernoulli effect, where air moving over the wings is at r
- Why does fluid pressure decrease as fluid velocity increases according . . .
Bernoulli's principle allows us to infer a decrease in pressure from an increase in velocity only when the internal energy of the pressure is the only possible source of the increase in kinetic energy but when the finger blocks the hole, wouldn't that add extra pressure on the fluid?
- Bernoulli equation and wind - Physics Stack Exchange
Bernoulli's equation does not state that a fluid in motion is at a lower pressure than a fluid at rest Rather, it relates pressure changes to changes in velocity If the upstream and downstream velocities are the same, Bernoulli's equation indicates that the pressures are the same I think that this is what is happening in your case, with perfect fluid flowing along a wall parallel to the
