Homework Statement
Torricelli's thereom is v = sqroot(2g(y2-y1)) where the velocity at the top is negligable compared to the velocity at the bottom (v).
If the velocity at the top is considered (v2) then v1A1=v2A2 is substituted into Bernoulli's to give
v1 = sqroot(2g(h2-h1)/1-(A1/A2)^2)
Homework Equations
The above equation says that if A1=A2 then the velocity at V1 is infinite. Is that right? How should this be interpreted?
To increase the velocity of v1 then I can increase the area of A1(bottom) to be closer to the area of A2(top) or increase the height (h2-h1). I could do this by adding an extended pipe the size of A1 down from A1. Is that correct? I am a little surprised that the velocity increases with the area (A1) increasing.
Thanks.
