All right. How does the flow rate in a pipe depend on its diameter?

好吧。管直径如何决定流量？

Today you learned how the urinary system regulates the production of urine, by maintaining a study glomerular flow rate.

今天你们学习了泌尿系统如何通过维持肾小球流速来调节尿液的产生。

Don't be surprised if you switch to a precision basket and you see your flow rate suddenly increase.

如果您切换到精密萃取头并看到您的流速突然增加，请不要感到惊讶。

The urethra's diameter also affects flow rate.

尿道的直径也会影响流速。

How's that for a flow rate equivalency?

流量当量如何？

We need to test the water flow rate .

我们需要测试一下水流量。

The flow rate of this material is very bad .

这流率。

Uh, remember that paper I had published last year on sediment flow rate?

记得我那篇沉积速率论文吗？

The data sheet shows that the flow rate of this material is very low.

性表显示，这种材的流性。

But this loss can be overcome if the flow rate in from the glacier aquifer is high enough.

但如果来自冰川含水层的流速足够高，这种损失是可以克服的。

This is called the mass flow rate, and it’s always going to be the same everywhere in the pipe.

这就是所谓的质量流量， 它在管道的任何地方总是一样的。

As sperm swim upstream, they make their way through secretion s that vary in thickness and flow rate.

霍普金：当精子向上游游时，它们会穿过厚度和流速各不相同的分泌。

This is called the mass flow rate, and it's always going to be the same everywhere in the pipe.

这称为质量流量， 它将保持固定在管的每位置。

See, Einstein's special theory of relativity shows that the rate time flows at depends on how fast you're moving.

看，爱因斯坦的狭义相对论表明，时间流逝的速度取决于你移的速度。

In doing so, the urethra harnesses the power of Torricelli's Law, which states that flow rate increases with container height.

在这样做时，尿道利用了托里切利定律的力量，该定律指出流量随着容器高度的增加而增加。

It’s the same thing we said before: The mass flow rate is the same for every point in the pipe.

这和我们之前说过的一样：管道中每点的质量流量都相同。

It's the same thing we said before: The mass flow rate is the same for every point in the pipe.

质量流量 它在管中的任何一点都保持不变。

Because if you kept the resistance the same you'd have to grind your 18 grams much much coarser to have a similar flow rate.

因为如果您保持相同的阻力，您必须将18克磨得更粗，才能获得相似的流速。

At the same time, operators  elected to open the service spillway gates to double the flow rate and accelerate the lowering  of the reservoir.

与此同时，运营商选择打开服务溢洪道闸门，使流量加倍并加速水库的下降。

It's all too common with cheap machines to have a different appearing flow rate just because the baskets don't match and that is unacceptable and extremely annoying.

对于便宜的机器来说，仅仅因为萃取头不匹配而出现不同的流速是常见的，这是不可接受的并且非常烦人。
