What is slurry technology? What is it used for? | The transportation of solids in water - 1. Paper Production - 2. Hydro-seeding - 3. Mining- Processing minerals |
What is density? | Density is the ratio of mass to volume |
What is buoyancy? | The tendency of an object in a fluid to rise or sink due to density differences with its surroundings |
What is Archimedes principle? | The buoyant force on an abject is equal to the weight of the fluid displaced by the object |
What is pressure? | The amount of force applied to a given area |
What are two effects of pressure? | 1. It causes our ears to pop when we change altitude quickly 2. Air Balloon increases in pressure and explodes |
What is parcels law? | When force is applied to an enclosed fluid the increase in pressure is transmitted equally to all parts of the fluid. |
What is a hydraulic system? | Transfer of energy from flow and pressure, not from the kinetic energy of the flow. |
What is compression? | The decrease in volume as a result of a force |
What is a pneumatic system? | A system that uses a gas, usually air, under pressure to transmit a force |
What is buoyant force? | s an upward force exerted by a fluid that opposes the weight of an immersed object. |
