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