What is the cause and what is the effect in the Bernoulli effect?
Oct 25, 2021 · 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 …
How much effect does the Bernoulli effect have on lift?
21 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 …
fluid dynamics - What's wrong with this argument that aerodynamic lift ...
Jul 19, 2015 · 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 …
On a hot day, when it's cooler outside than in; is it better to put a ...
This answer is contradicted by the experiments in this youtube video youtu.be/1L2ef1CP-yw. Blowing outwards is much more effective, and the Bernoulli effect means the impact is increased by …
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...
fluid dynamics - Are eductors working on the Bernoulli principle ...
Mar 21, 2016 · 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 …
Can you explain the perfume bottle with the Bernoulli effect?
Apr 15, 2019 · Someone explained the perfume bottle with the Bernoulli effect: squeezing the bulb over the fluid creates a low pressure area due to the higher speed of the air, which subsequently draws …
Is Magnus effect a corollary of Bernoulli principle?
Mar 23, 2015 · 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 …
thermodynamics - Bernoulli's principle, the Venturi effect, and ...
Apr 12, 2025 · The Bernoulli equation is derived from the : which, if you condense the notation a little bit look like: where is density, is fluid parcel acceleration and are forces acting on that particle (I …
Do helicopters and planes fly by different reasons?
Sep 14, 2020 · But the most voted answer to How much effect does the Bernoulli effect have on lift? says All of the lift depends on the Bernoulli principle, because speed and pressure are in trade-off, …
