SCIENCE QUIZ Define fluids. Fluids are materials that have no fixed shape and are free to flow such as liquids and gases. Define laminar flow. Laminar flow is a smooth pattern of flow. Define Turbulent flow. Turbulent flow is an irregular mixing flow pattern. State the particle theory of matter. -Particles are always moving. -Particles are attracted to each other. -Particles move faster when heated. -All matter is made of tiny particles. -Particles have empty spaces between them What is Viscosity? Viscosity is a measure of how easily a fluid's particles can slide past one another What is Flow Rate? Flow rate is a measure of how quickly fluids move measured in volume per unit of time. Ex: L/s What is the connection between viscosity and flow rate? The connection between viscosity and flow rate is that the flow rate mostly depends on the fluid's viscosity. Ex: Maple syrup vs water What is cohesion? Cohesion is a measure of how strongly the particles of a fluid attract each other. Ex: Carmel What is Adhesion? Adhesion is the attraction between the particles of one subtance and the particles of another substance. Ex: Adhesive glue Define fluid mechanics. Fluid mechanics is the study of how fluids behave both at rest and in motion. Define fluid dynamics. Fluid dynamics is the study of fluids in motion Fluid Dynamis is subdivided into 2 major areas; -Aerodynamics: the study of moving gases. -Hydrodynamics: the study of moving liquids. What are aeronautics Aeronautics is the study of flight. Controlling blood flow. If your blood clots too easily, then you need medicine to thin out the blood. But if your blood is too thin and does not clot at all you may need to take medicine to promote clotting.
