That’s called the kinetic energy density, and it’s the second term of Bernoulli’s equation.

这就是所谓的动能密度， 它是伯努利方程的第二项。

Bernoulli also came up with what we now know as Bernoulli’s equation.

伯努利还提出了我们现在所知的伯努利方程。

Bernoulli also came up with what we now know as Bernoulli's equation.

伯努利还放了什么 我们通过伯努利方程知道它。

Now, let’s look at a special case of Bernoulli’s equation, known as Torricelli’s theorem.

现在，让我们看一下伯努利方程的一个特例， 即托里拆利定理。

The first term in Bernoulli's equation takes that energy, and divides it by volume.

伯努利方程的第一项是 能量除以体积。

The first term in Bernoulli’s equation takes that energy, and divides it by volume.

伯努利方程中的第一项取该能量， 并将其除以体积。

That's called the kinetic energy density, and it's the second term of Bernoulli's equation.

这称为动能密度， 它是伯努利方程的第二项。

It’s exactly the same equation as the one we just found by using Bernoulli’s equation to describe the velocity of the water coming out of the spout.

它与我们刚刚通过使用伯努利方程找到的方程完全相同，用于描述从喷口流出的水的速度。

To better understand this, have a look at how the three forms of energy in a fluid are represented in Bernoulli’s equation: First, there’s pressure times volume.

为了更好地理解这一点， 请看一下伯努利方程中流体中三种形式的能量是如何表示的：首先，压力乘以体积。
