100
The movement of water molecules from a low to high solute concentration vs. the movement of particles from a high to low solute concentration.
What is the difference between osmosis and diffusion?
100
How atoms get "happy", or satisfy their full octet with 8 electrons.
What is bonding?
100
Mass per unit volume.
What is density?
100
Used for small particle filtration.
What is membrane filtration?
100
The name of the first icebreaker we played on Day 1.
What is Name Pyramids?
200
The equation for osmotic pressure.
What is \Pi=iMRT
200
Electrons located on an atom's outermost shell.
What are valence electrons?
200
A property of a fluid that describes its resistance to stress.
What is viscosity?
200
Material that passes through the membrane.
What is permeate?
200
The two components we found in the Brita filter.
What is activated carbon and ion exchange resin?
300
The dissociation of ions in solution, denoted by the variable "i".
What is the van't Hoff factor?
300
Depends on its dissociation in water.
What is a strong acid and strong base?
300
A fluid process in which there is no transfer of heat.
What is adiabatic?
300
The more effective filtration technique since it reduces fouling and scaling of the membrane.
What is tangential flow?
300
Experiment we did to understand Non-Newtonian Fluids and viscosity and density of fluids.
What is oobleck?
400
Form of energy due to thermodynamic properties of species in a mixture; the driving force for diffusion.
What is chemical potential?
400
Gives rise to material properties, electrical and thermal concepts, and chemical phenomenon.
What are electrons?
400
Fluids flow with this pattern at low speeds.
What is laminar flow?
400
Type of membrane filtration used in waste water treatment plants to purify/desalinate water.
What is reverse osmosis?
400
Kari, the graduate student who gave us the lab tour, used this programming system to control her membrane testing unit.
What is LabView?
500
Pressure you must overcome to push water back through the membrane, in the direction opposite to its natural flow.
What is osmotic pressure?
500
A molecule made up of carbons and hydrogens only.
What is a hydrocarbon?
500
Reduction in fluid pressure as a result of flow through a constricted pipe.
What is the Venturi effect?
500
Industries are turning to membrane filtration as an energy saving alternative to this common industrial separations process.
What is distillation?
500
This step in engineering design process is very important because it ensures the design will withstand every situation.
What is troubleshooting?
