Bernoulli’s Water Tank | Calculate Discharge Velocity

Use Bernoulli’s Law to solve for the discharge velocity of a frictionless (inviscid) fluid as it exits a reservoir which is some height h deep. The reservoir is commonly presented as a tank, or a bucket with some sort of hole or spigot for the fluid (typically water) to drain from. We use Bernoullis Equation to solve for the fluid speed as it exits the hole in the tank, bucket or reservoir. Stick around for Part 2 of this video where we will take a look at the total time it will take this tank to drain. This problem typically shows up in college physics, engineering, and fluid mechanics courses. It appears in Project Lead the Way, Principles of Engineering, AP Physics and some high school physics curriculums.
