Across
  1. 5. When a fluid rotates on an axis like a swirl
  2. 6. Push, pull, move – how things dance with force.
  3. 9. Sticking between unlike materials.
  4. 12. surfaces that consumes water, like sponges
  5. 13. Thick when still, runny when stirred, like ketchup.
  6. 15. studying how air moves around things
  7. 16. Liquid climbing thin gaps like it’s defying gravity.
  8. 17. movement a bird makes; used in airplanes for lift
  9. 22. The rule that what flows in must flow out.
  10. 24. How much fluid moves per unit time.
  11. 27. stress force making different layers of fluids slide39
  12. 30. surface water-hating surfaces; like in raincoats.
  13. 33. the process of water disappearing
  14. 34. Molecules spreading out on their own.
  15. 35. the harder study of fluids
Down
  1. 1. A gas that squishes when squeezed.
  2. 2. Like-with-like sticking (why drops hold together).
  3. 3. will it float or sink?
  4. 4. How easily a fluid passes through a material.
  5. 7. becomes thicker/solid when stirred
  6. 8. engineers pretending fluids aren’t millions of molecules
  7. 10. the easier study of fluids
  8. 11. bubbles in fluids which damage machines when they pop
  9. 14. Smooth path that fluid particles follow
  10. 18. Bulk movement of heat or stuff by flowing fluid.
  11. 19. Dimensionless number predicting flow chaos.
  12. 20. An upward force that prevents airplanes from falling.
  13. 21. the ranking of material fighters against compression
  14. 23. A fluid that obeys simple stress rules.
  15. 25. the laziness of a fluid as it moves
  16. 26. why airplane wings work (relationship with fluids and pressure!)
  17. 28. the man who discovered why things float
  18. 29. Flow that’s smooth, not chaotic.
  19. 31. How a fluid bounces back after stress.
  20. 32. How heavy a fluid feels for its size.
