Calculate the speed with which wafer emerges from a hole in a tank at which the gauge pressure is ` 3 xx10^(5) N//m^(2)` ?

Explanation

To calculate the speed at which water emerges from a hole in a tank given the gauge pressure of \( 3 \times 10^5 \, \text{N/m}^2 \), we can use Torricelli's theorem, which states that the speed of efflux of a fluid under the influence of gravity can be determined by the equation:

\[ v = \sqrt{2gh} \]

However, since we have the pressure instead of height, we can relate pressure to height using the formula:
