## Homework Statement

Figure P9.81 shows a water tank with a valve at the bottom. If this valve is opened, what is the maximum height attained by the water stream coming out of the right side of the tank? Assume that h = 8.0 m, L = 1.50 m, and = 30° and that the cross-sectional area at A is very large compared with that at B.

## Homework Equations

Bernouli's equation

P1 + 1/2(density)(v1)^2 + density(g)(y)= P2 + 1/2(density)(v2)^2 + density(g)(y)

## The Attempt at a Solution

0+0+density(g)(y)= 0+1/2(density)(v2)^2 + density(g)(Lsin30)

I tried solving for v2

I am stuck now at this step

used that v2 as v initial to find y by

vfinal^2= vinitial^2-2g(y final-y initial)

I am not sure but would v initial be the v2 I found? And is v final 0? Also what is y final and what is y initial?
