Aerodynamics 2
P+1/2 〖ρV〗^2= constant When the velocity of a flow increases its pressure decreases. Called stagnation pressure. Use the equation to measure the velocity of the air going into the Pitot tube with its stagnation point. A straw is an example. You suck out the air from the top part of the straw which makes a vacuum. The high pressure outside the straw forces the “drink” up the straw and into your mouth until pressure is equal and you finish your “drink”. Another is when a vacuum cleaner motor pulls the air out of the vacuum, this creates a low pressure area and pulls up dirt and small particles from whatever you’re vacuuming. Finally the upper atmosphere the higher pressure below pushes tiny particles into the atmosphere and
