Force due to the pressure difference between the upper and lower surfaces of the wings,created by different air speeds on the surface

Vedclass · Answer

(B) . The upper surface of the wing is more curved than its lower surface; therefore,the speed of air above the wings is larger than the speed of the air below the wings.According to Bernoulli's theorem,the pressure above the wings becomes less than the pressure below the wings.Due to this difference of pressure on the two sides of the wings,a vertical lift acts on the aeroplane.When this lift is sufficient to overcome the gravitational pull on the aeroplane,the aeroplane is lifted up and sustained in flight.

Explain with the help of Bernoulli's principle why a spinning ball follows a curved path during flight.

The reading of a pressure gauge connected to a closed tap is $3.5 \times 10^5 \, N/m^2$. When the tap is opened,the reading of the pressure gauge falls to $3.0 \times 10^5 \, N/m^2$. The velocity of water is ........ $m/s$.

Write the limitations of Bernoulli's equation.

Assertion $(A)$: The upper surface of the wing of an aeroplane is made convex and the lower surface is made concave.
Reason $(R)$: The air currents at the top have smaller velocity and thus less pressure at the bottom than at the top.
