Therefore, one cubic foot of air contains 1.2304 ounces and 1000 ounces of air will occupy 813 cubic feet. 2. Find the volume of jet fuel (17 ounces of jet fuel at 62.5% weight of water): For water, one cubic foot weighs 62.4 pounds and one pint equals one pound.
What is the weight of air?
We know that air weighs 14.7 psi or pounds per square inch at sea level – meaning about 15 pounds are pressing down on every square inch of you. In other words, that’s about the weight of car pressing down on you all the time!
How much does a cubic feet of air weigh?
FINAL ANSWER: 1 cubic foot of air at standard temperature and pressure assuming average composition weighs approximately 0.0807 lbs .
What does 1 pound of air weigh?
Converting to pounds (since the question was in English units I assume the answer is desired in English units) we get 0.0807 lbs. FINAL ANSWER: 1 cubic foot of air at standard temperature and pressure assuming average composition weighs approximately 0.0807 lbs.
What is a standard cubic foot of air?
Natural gas
For petroleum gases, the standard cubic foot (scf) is defined as one cubic foot of gas at 60 °F (288.7 K; 15.56 °C) and at normal sea level air pressure. ... A pressure 14.73 pounds per square inch (1.0023 atm; 101.56 kPa).
How much weight of air is always over your head?
1000 kg of weight of air is always over your head . Even though air molecules are too small to observe or to see all the molecules of air in the atmosphere above your head weight something .
What is the weight of air causes?
Air pressure is caused by the weight of the air molecules above. Even tiny air molecules have some weight, and the huge numbers of air molecules that make up the layers of our atmosphere collectively have a great deal of weight, which presses down on whatever is below.
Is it possible to weight air?
The density of air depends on pressure and humidity. 2) You can weight it on a scale . But be very careful about this! ... The container and the air inside will weigh the same, but the difference in the buoyant force will be the weight of one cubic foot of air.
Do air has weight?
Does air weigh anything? Air is usually invisible , so most of us don’t give it much thought at all. In fact, when students are asked about the mass or weight of air, many are perplexed. Air seems like it doesn’t have mass, but it does.
How much does a room full of air weigh?
So you need to know the density of air. As is turns out, the approximate density of air at sea level (and at 20 C) is 1.2 kilograms per cubic meter. m = 600 kilograms . So, the air in your room weighs approximately (depending on how wet it is, what temperature, etc) 600 kg.
What is the weight of 1 atmosphere?
It corresponds to the pressure exerted by a vertical column of mercury (as in a barometer) 760 mm (29.9213 inches) high. One standard atmosphere, which is also referred to as one atmosphere, is equivalent to 101,325 pascals, or newtons of force per square metre ( approximately 14.7 pounds per square inch ).
How much does the air in a tire weigh?
The volume difference is just 10 liters, which means that the air in the tire will mass about 26 grams , less than 0.1% of the total weight (30 kg = 30,000 g) we estimated for the tire + the wheel. Because of buoyancy effects, the air will only weigh 13 grams, less than 0.05%!
How many cubic feet are in a barrel?
| Cubic Feet US Barrels (Oil) | 1 ft3 0.18 US bbl oil | 2 ft3 0.36 US bbl oil | 3 ft3 0.53 US bbl oil | 4 ft3 0.71 US bbl oil |

How do I calculate CFM?
CFM = (fpm * area) , where fpm is the feet per minute. To find the cubic feet per minute, substitute the FPM value with the area after the area is squared.
How much water is in a cubic foot of air?
Moved aloft, the air expands to 3 cubic feet with each cubic foot containing 2 grams of water vapor. If you are trying to keep up with the water vapor (say in a neat one cubic foot package), you are going to have a major headache as the moving air expands and compresses with changes in height.
