A leakage begins in a water tank at position P. The area of cross section of the hole is very small compared to that of the tank.

If the initial gauge pressure at P was $5 \times 10^5 \text{ N/m}^2$ and the density of water is $1000 \text{kg/m}^3$ , what the velocity (in m/s) with which the water gushes out of the hole? Submit your answer to 1 decimal place.
