Dimensions, Variables, Si Units, British Units Flashcards
What are the basic and British units that go with these variables? (d, small l)
m - basic units
ft - British units
What is the variable, basic si unit and metric unit for Time?
variable - t
imperial system - s
metric system - s
What basic imperial and metric units go with the variable, T?
Metric - C
Imperial - F
What dimension goes with the metric and imperial variables, C and F?
Temperature
What are the variable, basic si unit and basic British units for, Area?
Variable - A
metric unit - m^2
basic British unit - ft^2
What dimension goes with the metric and basic British units m^3 or L and ft^3 and gal respectively?
Volume
What’s the difference between the variable for velocity and Volume?
Volume has a big “V” to substitute and velocity has a small “v”
“m/s” and “ft/s” are metric and imperial variables for what dimension?
Velocity
Why might people get velocity and acceleration confused?
Both are m/s or ft/s but acceleration is squared.
What dimension goes with the variable, basic si unit and imperial units, “a”, “m/s^2”, “ft/s^2” respectively?
Acceleration
Unlike every other dimension these three have variables that aren’t the starting letter what are they?
Density with p
Volumetric flow rate with F
Electric current with I
What dimension has the variable, imperial units and metric units of p, lb/ft^3, and kg/m^3 respectively?
Density
What are the variables, basic si unit and basic British units for mass?
Variable - M
Basic si unit - kg
Basic British unit - lb
What dimension has the variables F,W the imperial units lb and metric units N?
Force or Weight
What Dimension and Variable go with the metric units and imperial units of Pa[pascale] and lb/in^2 [psi] respectively?
Pressure
What are the variables, basic si units and basic British units for work, energy?
Variables - W
Basic si unit - J [joule]
Basic British unit - ft*lbf
Flow rate has what variable, basic British unit and metric units?
Variable - F
Basic British unit - ft^3/sec, gal/s
Metric unit - m^3/s
Why is electric currents imperial and metric units different from other units of measurement?
Because they are both the same A [ampere]
Why is voltage special?
Because all of its variables, basic si units and basic British units are - “V”
What is the variable and basic si and basic British units for resistance?
Variable - R
Basic si/ British units - (omega symbol) [ohm]
Power has the variable and basic British/si units of what?
Variable - P
Basic si/british units - W [watt]
What dimension has the variable, basic si unit and basic british units of F, m^3/min, ft^3/min (cfm)?
Volumetric flow rate
