Q. 16

A Gipsy car has a canvass top. When the car runs at high speed, the top bulges out. Explain.

Answer :

The Bernoulli’s principle is given by:



Now, above the canvas, velocity is high, thus pressure, . While inside the canvas, the pressure remains same as the velocity doesn’t change. The pressure inside is thus high as compared to outside and the top bulges out to balance this pressure difference.
