Physics: Incompressible water flows out of a large reservoir through a pipe that opens to the atmosphere 5.70 m below the level of the water in the reservoir. what is the speed of the water as it comes out of the pipe?

At least 15 meters above the ground because 15 m = 33 miles per hour...

Physics

10.575 m/s

Explanation:

According to the conservation of energy, the potential energy is equal to the kinetic energy.

m = Mass of water

g = Acceleration due to gravity = 9.81 m/s²

h = Height of water = 5.7 m

v = Velocity of water

PE = KE

$mgh=\frac{1}{2}mv^2\\\Rightarrow \not{m}gh=\frac{1}{2}\not{m}v^2\\\Rightarrow v^2=2gh\\\Rightarrow v=\sqrt{2gh}\\\Rightarrow v=\sqrt{2\times 9.81\times 5.7}=10.575\ m/s$

∴ Speed of water out of pipe is 10.575 m/s
