Pressure & Flow
What is Standard Atmospheric Pressure?
This protects a water heater from corrosion, by giving its material up in lieu of the tank.
What is a Sacrificial Anode?
The operation of a cooling tower during a hot summer is an example of this method of cooling.
What is Evaporation?
A ramp is an example of this kind of simple machine.
What is an Inclined Plane?
Water boils at this temperature.
What is 212°F?
This is caused by sudden changes of direction, or burrs in pipe, and disrupts laminar flow.
What is Turbulence?
When oxidation occurs on copper, it develops this hard, thin film, which protects the metal beneath.
What is Patina?
The rate at this a material conducts heat is dependent upon this quality of the material.
What is Thermal Conductivity?
Described as a relationship of the amount of force exerted, how far the force moves, and the time it takes to make the movement.
What is Power?
A property of a metal which indicates whether it is magnetic or not.
What is Ferrous or Non-Ferrous?
An instrument used for measuring the force a fluid would exert, when at rest, on a unit area.
Sometimes referred to with the misnomer Electrolysis, this reaction is responsible for the corrosion of dissimilar metals.
What is Galvanic Corrosion?
The maximum pressure for plastic piping is calculated at this average temperature.
What is 73°F?
A shovel is an example of this type of basic machine.
What is a Lever?
Any substance that has mass and occupies space by having volume.
What is Matter?
Though we often consider atmospheric pressure to be a constant, it can vary greatly with this.
What is Elevation?
This is a chart which describes a metal's relative nobility, which metals that are further apart being more reactive with one-another.
What is the Galvanic Series?
This phenomenon, which can occur when heated water under pressure is suddenly depressurized, can be a real danger in the field.
What is Steam Flash?
These can increase force, or change its direction, but never result in an increase to power or work.
What are Basic Machines?
A dimensionless unit defined as the ration of the density of a substance to the density of a reference substance.
What is Specific Weight?
Described as the quantity of fluid passing a certain point in a system, as measured in a certain period of time.
What is Flow Rate?
Corrosion which occurs by physical forces, and increases when the temperature or stress on a material increases.
What is Direct Attack?
This coefficient describes how much a material's length changes per degree change in temperature.
Counting the ropes that are attached to a load allows one to calculate this for a pulley.
What is Mechanical Advantage?
Hard water has excessive amounts of these two minerals.
What are Calcium and Magnesium?
