Can I assume that the velocity is the same?

Homework Statement

Calculate "H"

Homework Equations

Bernoulli
Manometry

The Attempt at a Solution

I have calculated that Q=0.06723 m^3 /s
If I apply Bernoulli in the surface of the tank A and in out of the pipe, I have: H =(velocity in the final part of the pipe^2)/(2g). I have assumed that the Velocity in the final part of the pipe It is the same velocity with which the water comes out. I did this because I can't know the presurre in the final part of the pipe, and out of the pipe the manometric pressure is zero.

So MY QUESTION IS: Is correct to assume that the velocities at these points (in the final part of the pipe, and just outside the pipeline are the same??

Sure, if you're neglecting the viscous frictional pressure loss.
