Physics Question on Bernauli Theorem

Water is flowing through a horizontal tube having cross-sectional areas of its two ends beings AA and AA' such that the ratio A/AA/A' is 55. If the pressure difference of water between the two ends is 3×105 Nm−23 \times 10^5\, N m^{-2}, the velocity of water with which it enters the tube will be (neglect gravity effects)

A

5 ms−15\, ms^{-1}

B

10 ms−110\, ms^{-1}

C

25 ms−125\, ms^{-1}

D

5010ms−150\sqrt{10} m s^{-1}
