## Homework Equations

Bernoulli's eq. p1+1/2pv1^2+ pgh1 = p2+1/2pv22 + pgh2

## The Attempt at a Solution

Tried to rearrange for velocity, I guess I did it wrong.

v= √2gh*rho2/rho1

( The square root should be a whole root, of like all the terms, not sure how do fix that part)

Did i rerarrange it wrong?

Umm . I got 17.5, and 49 (somehow) , maybe im pllugging things in right, but im not sure what the right answer is , 17.5 isnt for sure.
