Bernoulli
Term
One application of Bernoulli's equation shows that if water flows through a small opening out of the side of a large container the water will flow with the same speed it would have had if it had undergone free-fall vertically through the same height difference. This effect, which was discovered a century earlier than Bernoulli did his work, is known as _____'s Theorem.
