where ρ is the density of the moving fluid, h is the difference in height between the two points.
Pressure in liquids:
We'll use Bernoulli's equation to solve for the velocity.
The pressure is greater in the wider cross section. P2 is greater than P1.
The elevation at points 1 and 2 is equal, h1 = h2. Thus, we can drop the terms h1ρairg and h2ρairg.
Using Bernoulli's equation:
Air flows through the tube shown in the figure. Assume that air is an ideal fluid.
What is the air speed v1 at point 1?
