During windstorm, light roofs are blown off. Why? – InterviewSolution

1.	During windstorm, light roofs are blown off. Why?
Answer» During windstorm, the speed of the wind above the roof is more than the speed below the roof. According to Bernoulli's theorem, therefore, the pressure above the roof is less than the pressure below it. The higher pressure below the roof lifts the roof up and hence, it is blown off.
