To solve this problem it is necessary to take into account the kinematic equations of motion and the change that exists in the volume flow.
By definition the change in speed is given by
Where,
x= distance
final velocity
initial velocity
a = acceleration
On the other hand we know that the flow of a fluid is given by
Where,
A = Area
v = Velocity
PART A )
Applying this equation to the previously given values we have to
Therefore the velocity of the water leaving the hole is 17.48m/s
PART B )
In the case of the hole we take the area of a circle, therefore replacing in the flow equation we have to,
The diameter is 2 times the radius, then is m or 1.91mm
