Water containing air bubbles flows without turbulence through a horizontal pipe which has a region of narrow cross-section. In this region, the bubbles
move with greater speed and are smaller in size than in the rest of the pipe
move with greater speed and are larger in size than in the rest of the pipe
move with lesser speed and are smaller in size than in the rest of the pipe
move with lesser speed and are of the same size as in the rest of the pipe
Water flows through the tube shown. Area of cross-section of wide and narrow part are $5$ $cm^2$ $\&$ $2$ $cm^2$. The rate of flow is $500$ $cm^3/sec$. Find difference in mercury level of $U-$ tube .......... $cm$
The flow speeds of air on the lower and upper surfaces of the wing of an aeroplane are $v$ and $2v$ respectively. The density of air is $\rho $ and surface area of wing is $A$ . The dynamic lift on the wing is
The pressure of water in a water pipe when tap is opened and closed is respectively $3 \times 10^5\,N/m^2$ and $3.5 \times 10^5\,N/m^2$ . With open tap, the velocity of water flowing is ........... $m/s$
When drops of mercury are placed on a clean surface of glass, they merge and become single drop explain.
Can Bernoulli’s equation be used to describe the flow of water through a rapid in a river? Explain.
