What is the initial speed of the jet and what is the radius of the hole out of which the jet passes?

What pressure must the pump of the fountain supply? (Assuming that it sits just below the emerging jet).

At height 1.2 m., what is the speed of the jet, and what is the radius of the column of water? Ignore effects of turbolence and assume that the jet does not break up.

-My main difficulty with this problem comes when I apply Bernoulli equation to answer the second question and I get the clearly impossible result that the pump pressure is 0.

1) Should I consider atmosferic pressure?

2) Is the final pressure 0?

3) Can I calculate the initial speed by simply equating initial kinetic energy and final potential energy?

I am missing something and I don't know what it is. Can someone help me?

Thanks for paying attention to this thread.
