Bernoulli's fluid flow in a tube [desperate]

[erinec]

It is 2 days before final exam and I don't even know how to solve this. I am so screwed.

I tried every possible way for hours and hours but none of the answers match the correct answers shown above. I would be extremely thankful for your help.

This problem cannot be solved without the diameters of the pipe, or the exit pressure. To be honest, I'm not sure what you could have tried to get an answer.

IF you have the diameters. You use the conservation of mass to obtain the final velocity, assuming the fluid is incompressible, so mass flow is constant. From there, you have all but one (exit pressure) term in Bernoulli's.
