Question

By the applications of Bernoulli's theory
State the definition for ....


Blowing of roofs during heavy storms?

Answer 1

The reason why things like this happen is due to atmospheric pressure inside their houses. This concept is called Bernoulli's Principle states that pressure in a fluid decreases as the speed of the fluid increases. The difference between these pressures is called lift. The result from the winds of a hurricane or tornado passing over the house is a low-pressure area. The inside of the house has a high pressure area and tries to fill the low-pressure area. Because it is stuck inside the house it pushes or lifts the roof off.So, unless the house or building is well vented, the roof is more likely to blow off in a strong wind.

Answer 2

As u know pressure is inversly proportional to velocity. Hence during storms velocity of air is very small inside roof while outside speed is very high hence a net outward pressure is created which blow the roofs.ok if yet u have doubt u can comment on it ok.
