(N/A) No.
Bernoulli's equation cannot be used to describe the flow of water through a rapid in a river because the flow is turbulent. Bernoulli's principle is derived based on the assumption of steady,incompressible,and non-viscous flow along a streamline. In a river rapid,the water flow is highly irregular,chaotic,and turbulent,which violates these fundamental assumptions.

Water is pumped steadily out of a flooded basement at a speed of $10 \ m \ s^{-1}$ through a hose (tube) of radius $1 \ cm$, passing through a window $3 \ m$ above the water level. The power of the pump is (Assume $g = 10 \ m \ s^{-2}$, density of water $= 1000 \ kg \ m^{-3}$): (in $\pi \ W$)

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.

An aeroplane of mass $3 \times 10^4\,kg$ and total wing area of $120\,m^2$ is in a level flight at some height. The difference in pressure between the upper and lower surfaces of its wings in kilopascals is........... $kPa$ $(g=10\,m/s^2)$

To get the maximum flight (Magnus effect),a ball must be thrown as:
