1 cubic foot of air will support 62 lbs
a cubic foot of air weighs 7 grams
2 cubic feet
Molecules or moles? And in a cubic foot of what? Air?
One cubic foot is 28.32L
If you take the average weight of all of the molecules in one cubic foot of air and add them together you reach 0.0807 pounds. This number can fluctuate with temperature and variations in the composition in the air.
1 cubic foot = 1,728 cubic inches 1 gallon = 231 cubic inches = 0.13368 cubic foot 5 gallons = (5 x 0.13368) = 0.6684cubic feet, of anything, even empty space
According to the related link, PHYSLINK.COM, "1 cubic foot of air at standard temperature and pressure assuming average composition weighs approximately 0.0807 lbs". The weight of air is highly dependant on the air temperature and barometric pressure.
The major difference in air pressure and water pressure is the weight. Water is a lot heavier than air. One cubic foot of air weighs 1/12 of a pound. One cubic foot of water weights approximately 64 pounds.
The weight of styrofoam depends on the density of the styrene hydrocarbon from which it is manufactured and the volume of air bubbles trapped in the foam.
The induced air flotation machine was invented by William Fagergren in the 1930's in the Salt Lake Valley of Utah. Induced air means that the rotor for the froth flotation machine draws in atmospheric air, rather than having an air compressor or blower providing "forced air".
It depends on how tall it is.
To test number of particles per cubic foot air in a room
The average adult at rest inhales and exhales something like 7 or 8 liters (about one-fourth of a cubic foot) of air per minute. That totals something like 11,000 liters of air (388 cubic feet) in a day.
There can be no equivalence. A pound is a measure of mass whereas a cubic foot is a measure of volume in 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed. Consider a cubic foot of air. How many pounds? Next consider a cubic foot of lead. How many pounds?
None, since there can be no conversion. A kilogram is a measure of mass. A cubic foot is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. If you are not convinced, consider a cubic foot of air. How many kilograms? Next consider a cubic foot of lead. How many kilograms?
288 cubic feet of "air" or 19 cubic feet of pure oxygen .
.018btu/ft3 F -- It takes .018btu to raise one cubic foot of air 1 degree Fahrenheit.
One cubic foot of helium will lift 28.2 grams at sea level: (n cubic feet)(28.2 grams/cubic feet)(1/448 pounds/gram) = n * .06294 pounds This is a baseline formula, there are many variables that will affect the lift of helium in air such as air temperature, air pressure and humidity.
