All right, so here in a, this is the equation, the final equation that you will get from deriving a lot of different things.
00:10
So, for example, a1 is going to be pi times 0 .018 squared, which gives you 1 .01763 times 10 to the negative 3 meter squared.
00:22
A2 is pi times 0 .9 times 0 .10 to the negative 2 meter squared, which gives you 2 .5 -4 -3, 4 times 10 to the negative 4 meters squared.
00:30
Squared and then you do a2 over a1 and you get 0 .25.
00:34
And then using bernoulli's equation, p1 plus 1 half pv1 squared plus pgh1 equals p2 plus 1 half pv2 squared plus pgh2.
00:45
And h1 equals h2 equals h.
00:48
You're going to plug all this in, use the continuity equation.
00:52
Essentially just do a lot of deriving and you will fall at this equation in the end.
00:58
So just yes...
