1. The problem statement, all variables and given/known data The homework my professor gave me is.... We have a tank filled with a liquid, it has a hole at the bottom of the tank. The tank does not taper. the hole is at the bottom and not on the side. No extra pressure is applied to the liquid to help it drain and the top of the tank is open too. The top is labeled with an A for the area at the top of the tank. The height is on the side. The hole at the bottom of the tank is labeled a. He is wanting us to find the equations, the reason the letters have no values. I attached a picture of the tank/drawing and labeling. 2. Relevant equations I will list the questions here. 1. What is the velocity of "a"? 2. What is the time to drain the tank with initial velocity of "a"? 3. What is the actual time to drain entire tank? 3. The attempt at a solution 1. V2=√2χgχh 2. I have not found anyway to calculate yet. 3. V=Q/A I was curious to know if I was on the right track. It has been really tough trying to remember. Honestly I am not sure if i ever covered this before. Please help me.
