An airplane wing is curved on top and flat on the bottom. Air moving over the curved top has to travel farther and faster than the air passing underneath. According to Bernoulli, the fast air on top creates a zone of low pressure , while the slower air underneath creates high pressure . The high pressure pushes the wing upward, creating lift.
If you're interested in learning more about fluid mechanics, here are some recommended textbooks and resources:
Several free resources and downloadable PDFs offer textbook-quality content for free, making them a perfect alternative to a "for dummies" guide. fluid mechanics for dummies pdf
| Field | Application | |-------|-------------| | Civil engineering | Water supply networks, dam design, sewer systems | | Aerospace | Wing shape, rocket nozzles, fuel flow | | Biomedical | Heart valves, artificial blood pumps, breathing machines | | Automotive | Car aerodynamics (less drag = better fuel economy) | | Environmental | River flow, pollution dispersion, ocean currents |
When fluids are not moving, they still exert forces. This branch of study is called fluid statics or hydrostatics. Pressure: The Invisible Push Pressure ( ) is defined as force ( ) divided by the area ( ) over which it is applied: An airplane wing is curved on top and flat on the bottom
Textbooks like Fox’s Introduction to Fluid Mechanics or Munson are excellent, but they assume you love math. A "For Dummies" style PDF is different:
Why it matters: Blocked arteries (smaller radius) drastically reduce blood flow — that’s why stents are used to open them. The high pressure pushes the wing upward, creating lift
