Fluid property most related to flow? - ANSWER Viscosity
PRVs are used in wine fermentation to prevent over-pressurization from which of the follow-
ing yeast reactions? - ANSWER The yeast produces carbon dioxide during fermenta-
tion.
Metals with high hardness will also have which of the following characteristics? - AN-
SWER Strong intermolecular bonding, high tensile strength, high yield strength, and
high abrasion/scratch resistance.
If an aluminum crimp connector is used to connect a copper wire to a battery, what would
you expect to happen? - ANSWER Only the aluminum connector will corrode (alumi-
num is anodic(electrons removed from surface) and will corrode to protect the copper).
Glass is an amorphous material, which means that: - ANSWER It has no apparent crys-
tal structure.
The # of hydrogen atoms in a molecule of dodecane is: - ANSWER 12 (do-two, decane-
10)
Which analytical equipment provides the best method to analyze the Hg concentration to
PPM in a groundwater sample. - ANSWER Atomic adsorption unit.
Air from a 100 psig source is free-flowing down a long pipe discharging to the atmosphere.
This is an example of what kind of fluid flow? - ANSWER Compressible flow.
