Question

When strong/high-speed wind blows, an umbrella held upright at times gets upturned. Explain the reason.

Answer 1

An umbrella held upright at times gets upturned:

1. On a windy day, as we move while carrying an umbrella, it turns upside down because the winds pass at the top of the umbrella, creating a low-pressure area over the top.
2. The higher pressure below the umbrella causes the umbrella to flip upside down in order to maintain equilibrium and balance the pressure difference as a result of the pressure differential.
3. Low pressure is caused by a fast breeze passing over the umbrella. Consequently, the umbrella turns.
