1. The problem statement, all variables and given/known data A wide tank contains a non-viscous liquid. The surface of the liquid is at a height 0.5 m above a hole situated at the bottom of the tank. Assuming streamline flow, calculate the velocity of the liquid emerging from the hole. 2. Relevant equations P + 1/2 Dv^2 + Dgh = constant (?) 3. The attempt at a solution h=0.5 m non-viscous -> density unchanged Then? I can't continue.
