1. What is the mathematical formulation?
2. What is the primary field of application?
3. Why do airplane wings lift?
4. How does Bernoulli's principle help with everyday things like a shower curtain?

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the mathematical formulation?P + ½ρv² + ρgh = constant (for steady, inviscid, incompressible flow)
2. What is the primary field of application?Aerodynamics, fluid mechanics, and mechanical engineering
3. Why do airplane wings lift?The wing shape makes air move faster over the top than the bottom, so the pressure above is lower and the pressure below is higher, pushing the wing up.
4. How does Bernoulli's principle help with everyday things like a shower curtain?Fast water pushes air around, creating a low‑pressure area that pulls the curtain inward.

Static Pressure: The pressure exerted by a fluid at rest or the pressure component independent of fluid motion.
Dynamic Pressure: The pressure component due to the motion of the fluid (½ρv²).
Streamline: A curve that shows the direction of fluid velocity at a given instant in time.
