What seems to happen is that the wind against the front of the trailer pushes the front of the trailer back flex in the structure.
Roof pushed up or down bernoulli.
Bernoulli s principle as stated in the text assumes laminar flow.
It is a system of intake and exhaust.
This is solved using bernoulli s equation and the definition of pressure.
Thus the pressure inside the building is higher than on the outside.
My roof only does this when going down the road.
The classic example of bernoulli s principle involves airflow over airplane wings.
The effect is used to properly ventilate your attic.
What happens is the roof is pushed inward and collapses the wind inside the house blows out the roof from the inside the higher pressure inside lifts the roof off the walls friction rips up the roof and blows it apart.
This causes the streamlined flow to be pushed up even further so that pressure occurs on the windward slope.
First choose the bernoulli points one just inside the roof where the air is still point a and one just outside where the air is moving point b.
The roof is flat so the air pushing up from the inside is at the same depth as the air pushing down on the outside so tex y 1 y 2 tex.

This allows some slack in the roof.
Approximately what is the force due to the bernoulli effect on a roof having an area of 220 m 2.
This then allows it to balloon up.
I m also assuming that the velocity of the air inside the house is zero tex v 2 0 tex.
The physics of roof ventilation the bernoulli effect.
Since the air is still inside.
Bernoulli s principle still holds.
They are sucked off as the high winds passing over the roof tops lowers the pressure iaw bernoulli s principle.
If the slope of the roof is reduced a point will be reached at which pressure on the windward slope becomes zero.
If it is reduced further the flow boundary will at first be sucked down and will continue to flow along the slope and a.
You can t really see an issue when the trailer is parked.
Airplanes fly upside down etc.
When a strong wind kicks up the pressure outside drops but there isn t time for air to flow in and out of the house to cause the corresponding drop in the interior pressure.
That s why you get a pressure gradient across the roof.
According to bernoulli the faster flow over the top corresponds to a lower pressure and provides lift to the wing.
The bernoulli principal states that an increase in the speed of a fluid will also cause a decrease in its pressure.
This concept can be derived from newton s 2nd law of motion.
Storm winds blowing at high speed over a roof can destroy the roof of a closed up house because of bernoulli s principle.
Typical air density in boulder is 1 14 kg m 3 and the corresponding atmospheric pressure is 8 89 10 4 n m 2.
This will allow us to eliminate many of the terms.
So i can rearrange bernoulli s equation.
I doubt it s a leak but who knows.
