1. The problem statement, all variables and given/known data:

Use Bernoulli’s principle to obtain a relation between the speeds of water at points A and B, vA and vB, in terms of the acceleration of gravity g and the height of the water column h. Your expression should be of the form: vb^2-va^2 =

Let’s do a numerical check that your equation is correct. If the height of the water level is h = 27 cm, what is the value of vb^2-va^2, in SI units?

2. Relevant equations

3. The attempt at a solution

I really have no idea where to start, to me, the question doesn't seem really obvious. I just need this last problem solved to be permitted in to lab on Monday morning. Please help me in any way, thank you so much!

This is what I have as bernolli's equation in my notes, but how do I use any of this to solve for vb^2-va^2????

P1+1/2pv1^2+pgy = P2+1/2pv2^2+pgy

I know P=pressure

p=density

y= height

Please please please help!!!
