H2O
This physical principle underlies most of fluidic circuitry.
What is Coanda effect?
This is the process whereby molecules move from areas of high concentration to areas of lower concentration.
What is Diffusion?
I said that the pressure of a liquid will be the same at any given depth regardless of the containers shape.
Who is Pascal?
This happens to the temperature of the surrounding air during the evaporation of water
What is: The adjacent air is cooled?
Boyle said that when volume goes down, this goes up (an important concept to understand when dealing with compressed gases)
What is the Pressure?
This is the force that is responsible for the spherical shape of liquid droplets.
What is Surface Tension?
This state of matter exhibits rapid, random motion with frequent collisions.
What is a gas?
I said that a flowing fluid’s lateral pressure must vary inversely with it’s velocity.
Who is Bernoulli?
This happens to the temperature of the surrounding air when you have condensation.
What is it warms the adjacent air?
Gay Lussac said that when the temperature goes up, so does this (another important concept to understand when dealing with compressed gases).
What is pressure?
This is the change in state of a substance from liquid to gaseous form occurring below its boiling point.
What is Evaporation?
This scientist said that the rate of diffusion of a gas is inversely proportional to the square root of it’s gram molecular weight.
Who was Graham?
I had to go an show up my friend Bernoulli by modifying his air entrainment system. I widened the tube after the jet to restore the pressure to pre-jet levels.
Who is Venturi?
This is the physical process whereby the gaseous form of a substance is changed back into its liquid state?
What is Condensation?
He said that how much gas will dissolve in a liquid is dependent on the solubility coefficient of the gas and the pressure over the liquid.
Who is Henry?
An important concept for oxygenating our patients.
This is the term for the actual content or weight of water present in a given volume of air.
What is Absolute Humidity?
Gases lack any inherent boundaries so they are easily what?
What is compressed and expanded?
OK…so I am not Italian, but I did say that the pressure below a submerged object always exceeds the pressure above it creating an upward or supporting force.
Who is Archimedes?
These are the forms of vaporization.
What are: Boiling and evaporation?
He said that if you increase: the viscosity, tube length, flow, or decrease the radius of a tube, the driving pressure will have to increase to maintain the same flow.
Who is Poiseuille? This helps us understand how secretions, inflammation and mucus plugs effect the patient's ability to breath as well as how much pressure on the ventilator we will need to set to overcome these findings.
This is the relative humidty (RH) of a volume of gas when its water vapor content equals its capacity.
What is 100%?
According to Graham, diffusion is based on kinetic activity, so anything that increased molecular activity will quicken diffusion. Name 2 ways that you can increase molecular activity.
What is heating and mechanical agitation?
I am Scottish and never married again after the passing of my wife, I said that light gases diffuse rapidly and heavy gases diffuse slower.
Who is Thomas Graham? Graham's Law
These things happen when a gas with a RH of 100% is cooled (name at least 2 things).
What are: Condensation on surfaces, visible droplet formation, and warming of the adjacent air?
What does the First Law of Thermodynamics say?
What is “Energy can neither be created nor destroyed, only transformed in nature”?
