1. The problem statement, all variables and given/known data A container is filled with liquid, density d. The depth of the liquid is h. A narrow, horizontal, tube at the bottom of the container is letting the liquid flow out at a speed v. The height of the liquid is kept constant. What is the velocity of the liquid flowing out of the tube? 2. Relevant equations Bernoulli's equation: p + (1/2)dv^2 + dgh = constant 3. The attempt at a solution I really don't know how to do this! I know the answer is (2gh)^(1/2), but i don't know why that is, as my textbook has no examples. Could someone please explain how to do these kinds of problems?
