Now, for this problem, we are asked what causes cavitation.
00:04
I'll start by drawing the phase diagram for water, for example.
00:10
You usually have something like that.
00:13
And you will see that if this is 101 kilo -pascal, this will usually correspond to 100 degrees c.
00:23
And that's why we usually just say, oh, the boiling point of water is 100 degrees c.
00:27
But is that true? the truth is the boiling point of water is 100 degrees c.
00:33
At 101 kiosk.
00:36
Meaning that if at this same temperature, the same temperature, but i reduce the pressure to say 50kcal.
00:46
Now you will see that this side is liquid, this side is vapor...
