Water stands at a depth in a large, open tank whose side walls are vertical (Fig. P12.89). A hole is made in one of the walls at a depth
below the water surface.
(a) At what distance from the foot of the wall does the emerging stream strike the floor?

ANSWER:Solution 89P
Introduction
At first we have to calculate the range first and then we have to calculate the another height from which the range will be same.
Step 1
From the bernoulli's equation we can write that
In the given problem at the surface of the water we have
And
Near the hole we have
And
So from the above equation we get
