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 governing principle?Fluid admission driven by a pressure differential between external and internal environments
2. What is the pressure generation?Can be active (mechanical systems) or passive (ram/hydrostatic pressure)
3. How does an intake let air or water into a machine?It works because the pressure inside the machine is lower than outside, so the fluid moves in. Machines can create this pressure difference with things like rotating blades or a piston.
4. Why do airplane intakes need to be shaped specially?Airplane intakes are shaped to slow down fast air so it can enter the engine safely. This helps the engine use the air efficiently and reduces damage from shock waves.

Pressure Differential: The difference in pressure between two points, driving fluid flow.
Ram Pressure: The dynamic pressure experienced by an object moving through a fluid, proportional to fluid density and velocity squared.
Hydrostatic Pressure: The pressure exerted by a fluid at rest due to the force of gravity.
Flow Rate: The volume of fluid that passes through a given cross-sectional area per unit of time.
