Which direction will a truncated cone be pushed by airflow?
Consider the shape below, with the bottom and top faces being holes.
Imagine we hold the shape in place and blow a wind into the big hole.
The air will exit the small end at a higher velocity due to ...

Measuring Bernoulli in airplanes
One common explanation for airplane lift is that air pressure over the wing both moves faster and has lower pressure, a la Bernoulli. A very different explanation is that air is deflected downward by ...

Why does Wind Velocity over a wing to increases and what is its cause?
Why does wind velocity increase over a wing?
Also I have a bit of a paradox, people explain lift by saying there is a lower pressure region on the top of the airfoil and a higher pressure region on ...

How does pressure become velocity in a jet engine axial turbine?
All right. Here's what I understand about axial turbines:
It is an axial compressor in reverse.
An axial compressor forces air to flow in an increasingly tight space, where there is not enough ...

Why can a helicopter fly upside down?
I saw images and video clips of helicopter flying upside down, so it can't be bernoulli principle or angle of attack of the rotary blades. So how can the upside down helicopter provide lift in this ...

Principle of Lifting of an Aircraft [duplicate]
While using the Bernoulli's equation to deduce the upthrust on an aircraft , a statement is always made that
The air particles going above th wing have to cover a greater distance in same time than ...

How powerful can the vacuum from an open aircraft window be?
It has been an item of folklore that a "pressurized" aircraft cabin, if punctured will force people through the aperture, a la Goldfinger. However, obviously the pressures inside the cabin (12 PSI) ...

What happens if a helicopter's propeller spins in reverse?
I know airplanes and helicopters fly thanks to the same principle, the Bernoulli Principle. The wings and blades are designed so that the air travels faster across the up side than it does on the ...

Why does moving air have low pressure?
According to Wikipedia lift in an aircraft is due to an area of low pressure formed above the wings of an aircraft due to the fast moving air there. So why exactly is an area of low pressure created ...

How much effect does the Bernoulli effect have on lift?
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 ...
