Question:
Water is flowing through a horizontal tube having cross-sectional areas of its two ends beings $A$ 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 (neglect gravity effects)

Bernauli Theorem
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. The principle is named after Daniel Bernoulli who published it in his book Hydrodynamica in 1738.
