**2. Bernoulli and continuity equations**

**3.**

p_1 = rho*gh_1

p_2 = rho*gh_2

p_2 = p_1 + 0.5rho*v_1^2 + 0.5rho*(A_1/A_2)^2 * v_1^2

I know those are correct.

Substituting for p_1 and p_2, and solving for v_1 I obtain:

2g(h_2 - h_1) / [1-(A_1/A_2)]

all that under a square root.

No idea why I am getting it wrong. Should h_2 - h_1 just be h??
