Wind Blowing Off A Roof Physics

Ii a 180 km h wind blowing over the flat roof of a house causes the roof to lift off the house.

Wind blowing off a roof physics.

Physics fluid flow 1 of 7 bernoulli s equation. The air pressure above the surface is lower compared to that underneath. If the strong wind blows all day. If the house is 6 2 m x 12 4 m in size estimate the weight of the roof.

This difference of pressure causes an upward thrust and the roof is lifted up. Assume the roof is not nailed down. 20 when wind blows at high velocity roof tops are blown off because pressure a outside is more than inside the roof b inside is more than outside the roof c increase due to wind velocity d is exerted by air from outside. The high wind blowing over the roof creates a low pressure in accordance with bernoulli s principle.

But at the corners and at the edges of the roof typically by the very nature of the wind blowing across the roof it exerts a higher pressure depending on the way the wind blows the shape of the roof and the location on the roof there will be negative pressure suction or positive pressure pushing like when the wind slaps your. This cause the roof to blow off. Physics fluid flow 5 of 7 bernoulli s equation duration. Assume the roof is not nailed down.

How strong winds from tornadoes and hurricanes can lift off roofs with overhangs. The aeroplane work in the same principle lower pressure on top surface. High winds are one of the most common causes of shingles blowing off during a storm. In maine exposure to high winds and the harsh winters can all work against the longevity of your shingles.

The pressure below the roof is equal to the atmospheric pressure which is now larger than pressure above the roof.
