I’ll need pen and paper for this. At first glance, assuming that the level remains constantly full, the velocity of the middle hole is the velocity of the top hole times the square root of 2, and the bottom hole velocity is that of the top times the square root of 3.
And then there’s the number of seconds it takes for each stream to reach the bottom, with the middle stream taking the square root of two longer than the bottom, and the top by a factor of the square root of three.
Now multiply time and velocity to get distance:
Top= 1 x sqrt(3)
Middle = sqrt(2) x sqrt(2)
Bottom = sqrt(3) x 1
The professor is right. The middle stream goes furthest.
