1. The problem statement, all variables and given/known data 2. Relevant equations Bernoulli: p1+½ρU12+ρgz1=p2+½ρU22+ρgz2 Continuity: Q=U1A1=U2A2 Area=CC*(¼πd2) 3. The attempt at a solution I attempted to apply the Bernoulli equation, making point 1 the top surface of the left hand side and point 2 the instant at the sharp edge. However I ended up with; pA+ρgz=p+½ρU2 Normally when it is not submerged, the formula can narrow down to U=√2gH, where H=z in this case, but I'm not sure how to eliminate the pressure in the liquid. Is liquid also trying to move from the right to the left?
