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........... $kPa$ $(g=10\,m/s^2)$

In the diagram shown,the difference in the height of the liquid columns in the two tubes of the manometer is $5\, cm$. The cross-sectional areas of the tube at $A$ and $B$ are $6\, mm^2$ and $10\, mm^2$ respectively. The rate at which water flows through the tube is ........ $cc/s$ $(g = 10\, m/s^2)$.

$A$ horizontal pipe of non-uniform cross-section allows water to flow through it with a velocity $1 \ m/s$ when the pressure is $50 \ kPa$ at a point. If the velocity of flow has to be $2 \ m/s$ at some other point,the pressure at that point should be: (in $kPa$)

What type of fluid can be applied in Bernoulli's equation?

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 $(g = 10 \, m/s^2)$.

Bernoulli’s theorem is a consequence of
