1. The problem statement, all variables and given/known data: There is tank with a certain depth with water that is exposed to air. There is a hole at the bottom of the tank. Using Bernoulli's equation, we can find the efflux speed. density of the water * gravity * depth = 1/2density of water * velocity ^2. This will give us the velocity of the water at the bottom of the tank which is V= Squareroot of (2*gravity*depth). My question is now, what would be the velocity of the water at the top as it is draining. I believe we can use pascals law where Flow(area times velocity)= Flow2(area2 times velocity). Since the area of the top of the water is bigger, the velocity of the water at the top draining would be smaller than the efflux velocity? Do I have the correct interpretation?
