Chapter 10, Problem 38P

To determine

To Calculate: The velocity of the water.

Answer to Problem 38P

  $9.5\text{m/s}$

Explanation of Solution

Given info:

Depth, $h=4.6\text{m}$ and ignore the viscosity.

Formula used:

The velocity of the water is given as,

  $v=\sqrt{2gh}$

Where, $h$ is the height of the water above the hole.

  $g$ is the acceleration due to gravity.

Calculation:

Substitute the given values in the formula, then the velocity is,

  $\begin{array}{c}v=\sqrt{2gh}\\ =\sqrt{2\times 9.8\times 4.6}\\ =9.5\text{m/s}\end{array}$

Conclusion:

The velocity of the water is $9.5\text{m/s}$ .
