So you know where to find the absolute pressure in the pipe flow here, labeled by the green arrow we're gonna do is we're essentially just going to take the difference in pressure from the right branch on the left branch.
00:15
So what i'm gonna do first is i'm gonna write an expression that, uh, represents the pressure at the bottom of the pipe on this is due to that right branch here that's only filled with water.
00:29
So we have to take into account.
00:31
Of course, the atmospheric pressure on and then we're simply going to write our out our equation for delta p retake the density times g, gravitational acceleration, times the height.
00:45
Jonas cases the height of the full columns of the age two plus age three.
00:55
And we're pulling in for the values that we know.
00:58
What we get is an absolute pressure of 109 0.1 kilo pascal's.
01:08
But we still have to account for pressure due to this left branch here that's partially filled with oil.
01:16
So the absolute pressure pipe would be equal to the pressure from the right branch which we found represented by pb.
01:28
The pressure at the bottom.
01:30
Um, we're gonna subtract the delta p as a result of this wheel water column on the left so we'll start with the little bit of water pressure due to that...
