A water tank is constructed on the top of a building. With what speed will the water come out of a tap 6.0 m below the water level in the tank? Assume steadyy flow and that the pressure above the water level is equal to the atmospheric pressure

Explanation

To solve the problem of determining the speed at which water will come out of a tap located 6.0 m below the water level in a tank, we can use Torricelli's theorem. This theorem states that the speed \( v \) of efflux of a fluid under the influence of gravity through an orifice is given by the equation:

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

where:
- \( g \) is the acceleration due to gravity (approximately \( 9.81 \, \text{m/s}^2 \), but we can use \( 10 \, \text{m/s}^2 \) for simplicity),
