What happens to the air pressure of an air parcel as it flows up the side of a mountain?
What happens when a steadily flowing gas flows from a larger diameter pipe to a smaller diameter pipe what happens to its pressure and It's speed?
What happens to the carbon dioxide in the blood when it flows through the capillaries in the alveoli?
The pressure pushes it around depending on how high or low the air pressure is. ANSWER Air moves from areas of higher pressure to areas of lower pressure. If you have a water balloon and you squeeze it, the area where your fingers are is similar to a high pressure zone. The water then flows away from your fingers to the lower pressure areas of the balloon. That is how air flows in the atmosphere…
When a steadily flowing gas flows from a larger diameter pipe to a smaller diameter pipe what happens to its speed its pressure and the spacing between its streamlines?
Not directly, although oddly enough, it does keep air from flowing up out to space. Air flows as wind as a result of horizontal pressure differences in the atmosphere. The greatest and most obvious pressure difference at all times is the vertical pressure difference. Gravity happens to balance this vertical pressure gradient force almost perfectly, keeping the atmosphere in hydrostatic equilibrium.
