So for this problem, you can see from the chart that kinetic energy at point one, with kinetic energy density at point one, which is k1, is greater than k2.
00:11
So this actually means v1 is greater than v2.
00:17
And also, it is given that potential energy density at point one equals potential energy density at point two equals zero.
00:31
And the chart shows that the pressure difference between 0 .1 and 0 .2 is actually less than 0.
00:40
That means p1 is actually less than p2, right? so from here, over here, y1 equals y2 equals 0.
00:53
Now, we can actually write down the bernal equation as kinetic energy at 0 .1 plus p1, minus p2 equals k2.
01:07
All right.
01:09
And you know, you can just substitute the value...
