<question: The density of air is
A: How much air weighs per cubic foot
B: How much volume one pound of air occupies
C: The ratio of the weight of water to that of the same volume of water
D: The ratio of the amount of water vapor contained in a cu. ft. of air to the amount of moisture held
at saturation ✔Correct Answer-A: How much air weighs per cubic foot
The specific volume of air is
A: How much air weighs per cubic foot
B: How much volume one pound of air occupies
C: The ratio of the weight of water to that of the same volume of water
D: The ratio of the amount of water vapor contained in a cu. ft. of air to the amount of moisture held
at saturation ✔Correct Answer-B: How much volume one pound of air occupies
The relative humidity of air is
A: The percent of moisture air is holding as opposed to the amount it could hold if it were saturated
B: Always less than 100%
C: The most accurate measurement of how much water vapor is in a given body of air
D: Used as a multiplier to size humidifiers ✔Correct Answer-A: The percent of moisture air is
holding as opposed to the amount it could hold if it were saturated
As air is heated it
A: Contracts
B: Expands
C: Does not change its volume
D: Becomes more dense ✔Correct Answer-B: Expands
The air pressure in a sealed balloon is
A: Static pressure
, B: Velocity pressure
C: A combination of static and velocity pressures
D: None of the above ✔Correct Answer-A: Static pressure
A blower connected to a length of duct
A: Creates static pressure which is then converted to velocity pressure
B: Creates velocity pressure directly
C: Creates resistance to the flow of air
D: None of the above ✔Correct Answer-A: Creates static pressure which is then converted to
velocity pressure
Velocity pressure is determined by
A: Subtracting static pressure from total pressure
B: Subtracting total pressure from static pressure
C: Dividing the total pressure by the static pressure
D: Subtracting the traverse pressure from the velocity ✔Correct Answer-A: Subtracting static
pressure from total pressure
Velocity pressure can be mathematically converted to
A: CFM
B: FPM
C: Relative humidity
D: Inches of mercury vacuum ✔Correct Answer-B: FPM
fpm = 4005 x (sqrt of Vp)
An inclined manometer is basically
A: A U-tube manometer tilted at a steep angle
B: A hygrometer on a stand
C: A digital micron gauge
D: A type of sling psychrometer ✔Correct Answer-A: A U-tube manometer tilted at a steep angle
