  1. 4. States that any object fully or partially submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object.
  2. 5. The action or property of molecules sticking together, being mutually attractive.
  3. 6. A hypothetical fluid with no viscosity and no resistance to shear stress.
  4. 7. A type of fluid flow where every particle follows a smooth path.
  5. 9. The force exerted by a fluid on an object moving through it due to viscosity.
  6. 11. A law stating that the force of viscosity on a small sphere moving through a viscous fluid is proportional to the sphere's velocity and radius.
  7. 14. The SI unit of pressure, equivalent to one newton per square meter.
  8. 17. An instrument measuring atmospheric pressure.
  9. 18. The constant speed that a freely falling object eventually reaches when the resistance prevents further acceleration.
  10. 22. States that a change in pressure at any point in an incompressible fluid is transmitted throughout the fluid.
  11. 24. The measure of the relative volume change of a fluid as a response to a pressure change.
  12. 25. The property of a fluid that resists the force tending to cause the fluid to flow.
  13. 26. The force exerted on an object that is partly or wholly immersed in a fluid.
  14. 27. The ability of a liquid to flow in narrow spaces without the assistance of external forces.
  15. 28. The elastic tendency of a fluid surface which makes it acquire the least surface area possible.
  16. 29. The pressure of a gas is inversely proportional to its volume at a constant temperature.
  17. 30. The force exerted per unit area.
Down
  1. 1. The study of fluids and the forces on them.
  2. 2. The pressure exerted by a fluid at equilibrium at a given point within the fluid.
  3. 3. The ratio of the viscosity of a fluid to its density.
  4. 8. States that the pressure in a fluid decreases as the fluid's velocity increases.
  5. 10. The pressure of a fluid in motion, associated with its velocity.
  6. 12. A flow regime characterized by high momentum diffusion and low momentum convection.
  7. 13. A type of fluid flow characterized by chaotic changes in pressure and flow velocity.
