It states that along any streamline (a streamline is the path traced out by arbitrarily small element of the fluid), the following equality holds:
p + ½ρv² + ρgz = constant
p - static pressure
ρ - density
v - speed
g - gravitational acceleration
z - vertical position
The constant is the total pressure also called the stagnation pressure. This equation was derived for theoretically "frictionless" or zero viscosity fluids but it is a fair approximation for real fluids where friction is not playing a significant role in the flow. For the case of gases the last term is negligible, so you can say that wherever the flow speed decreases along that streamline, the static pressure will increase. Why along the streamline? Because that constant is only a constant for a given streamline.
the correct answer is speed!
Pitot tube on a plane to measure airspeed.
Yes. A+
velocity and pressure have inverse relation. when velocity increases then pressure at that point decrease and vice versa.
because it flows from cold to warm areas and around solid objects. Which is what bernoullis principle is based on. the basis of flight..

That's "principle", not "principal". The idea is that the airplane's wings are shaped in such a way that the air moves faster on the top than on the bottom. As a result - and applying Bernoulli's principle - there is less pressure on the top of the wings.

The Statement: For the streamline flow of an ideal fluid,the sum of the potential energy,kinetic energy and the pressure energy per unit mass remains constant.
