Bernolli's Equation: vb^2-va^2 = ?
1. Homework Statement :
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. Homework 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 into 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!
