Presentation Transcript

  1. How we take what we know and put it into action! Technologies & Fluids

  2. Detergents • How do they work? • Something that removes dirt? • But how? • Contain something called a surfacant • These attach to dirt and oils • Surrounds them so they cannot reattach to the clothes (Suspension Agent) • Washed away

  3. Diving & Compression • How do humans breath underwater? • SCUBA • Self-Contained Underwater Breathing Apparatus • But what about the pressure as you descend?

  4. Diving & Compression • Deeper you go = more pressure • As the pressure builds up it causes nitrogen gas to dissolve in our blood and tissues at a much higher concentration than normal • We learned this the hard way as humans …

  5. Diving & Compression • If you ascend slowly, the gas leaves your body normally … that’s good • If you ascend too quickly the pressure drops rapidly and you get a decompression sickness known as “The Bends”

  6. The Bends • A rapid change in pressure causes the gas to bubble out of the blood and tissue • It can collect in your body and cause considerable pain • You can die if it isn’t treated

  7. The Bends – Treatment • So how do you treat it? • Hyperbaric Chamber • Diver goes in • Chamber is sealed • Pressure is created that forces the gas back into the blood stream and tissue • Slowly decreasing the pressure then releases the gases safely • Cured

  8. The Bends • Here is a video clip of a real world scenario of someone who experienced the Bends … BBC - The Bends

  9. Moving Fluids • How do you move fluids & gasses? • Pumps • A device that moves a fluid through, or into, something • What is a naturally occurring pump?

  10. The Bicycle Pump • One of the most common pumps • Works on the piston basis … like so …

  11. Pipeline Pigs • A computerized unit used to monitor and clean pipelines • Propelled by moving gases in the pipeline • Fun movie time

  12. Valves • These control or regulate the amount of flow • Taps in your bathroom sink • Faucet for outdoor hose • Different types of valves
