(N/A) Bernoulli's equation is based on the assumption of an ideal fluid. Its limitations are as follows:
$1$. It is valid only for incompressible,non-viscous,and steady (streamline) flow of fluids.
$2$. It does not account for energy loss due to viscosity or friction between fluid layers.
$3$. It ignores the energy dissipated as heat during fluid flow.
The uses of Bernoulli's equation include:
$1$. It is used to calculate the velocity of efflux (Torricelli's Law).
$2$. It explains the working principle of a Venturi meter,which is used to measure the flow rate of a fluid.
$3$. It explains the aerodynamic lift on an airplane wing.
$4$. It is used in the design of atomizers and Bunsen burners.

The speeds of air above and below the wing of an airplane are $120\, m/s$ and $90\, m/s$,respectively. The density of air is $1.3\, kg/m^3$. If the wing has a length of $10\, m$ and a width of $2\, m$,the pressure difference between the top and bottom of the wing is ......... $Pascal$.

What is the nature of the pressure-distance graph for the pipe shown in the figure?

Water is flowing through a horizontal tube having cross-sectional areas of its two ends as $A$ and $A'$ such that the ratio $A/A'$ is $5$. If the pressure difference of water between the two ends is $3 \times 10^5 \, N \, m^{-2}$,the velocity of water with which it enters the tube will be ......... $m \, s^{-1}$ (neglect gravity effects).

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