Y sub 1 is equaling y sub 2 because the tube is horizontal.
00:04
So when we apply brunuli's equation, this will become p.
00:07
Sub 1 plus 1 half row v.
00:12
Sub 1 squared, equaling p sub 2 plus 1 half row v.
00:18
Sub 2 squared.
00:19
And so v.
00:20
2 squared minus v.
00:22
Sub 1 squared is going to be equaling to 2 times p sub 1 minus p sub 2, divided by row, the density.
00:32
And so this would be equaling 2 times 1 .20 times 10 to the third pascal's divided by 7 .00 times 10 to the second kilograms per cubic meter.
00:51
And this is giving us 3 .43 meters squared per second squared.
01:00
Now, from the continuity equation, we have that v .2 is equalling v.
01:06
Sub 1 multiplied by a sub 1 divided by a sub 2.
01:13
And so this would be equalling r sub 1 divided by r sub 2, quantity squared times v sub 1.
01:24
This is equalling 2 .40 centimeters divided by 1 .20 centimeters...
