What is the weight of 80 cubic feet of air?

FINAL ANSWER: 1 cubic foot of air at standard temperature and pressure assuming average composition weighs approximately 0.0807 lbs. This one doesn't have an answer that is exact or necessarily correct as air is a composite mixture of various gases and this mixture can change due to an enormous quantity of variables.

How many pounds equal a cubic foot?

Air weighs 0.0012929 gram per cubic centimeter or 1.2929 kilogram per cubic meter, i.e. density of air is equal to 1.2929 kg/m³. In Imperial or US customary measurement system, the density is equal to 0.080713 pound per cubic foot [lb/ft³], or 0.000747344 ounce per cubic inch [oz/inch³] .

How much weight can 1 cubic foot hold?

What is the weight of 1 cu ft of air? 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 …

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!Apr 9, 2016

What is a standard cubic foot of air?

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. The pressure definition differs between sources, but are all close to normal sea level air pressure.

How do you find the weight of air?

Standard atmosphere pressure ( at 0 deg C and sea level) is about 14.7 pounds per sq inch or 100,000 pascals. So for this standard pressure, simply multiply the HORIZONTAL area (in sq inches) by 14.7 to get the force or “weight” of the air.

How do you calculate the weight of compressed air?

Air is about 80 percent nitrogen and 20 percent oxygen by volume. Take 80 percent of nitrogen's molecular weight (0.8 * 28 = 22.4). This is the weight contribution that nitrogen will provide to air's molecular weight. Take 20 percent of oxygen's molecular weight (0.2 * 32 = 6.4).Jan 9, 2002

What does 1 cubic meter of air weigh?

1.222 kilograms per cubic meter

At sea level, the density of air is 1.222 kilograms per cubic meter. There are 454.5 grams per pound which gives 28.35 grams per ounce. So 1.222 kilograms is equal to 43.1 oz of air occupying 1 cubic meter.May 13, 2021

How much does a cubic foot of dry air weigh?

approximately 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 the weight of the air in the room?

For extra fun: atmospheric air is ∼14.7psi, so the total force on the floor of the room (20 x 20) is more than 800,000 pounds!Apr 3, 2015

Does air have mass or weight?

You'll also notice that a balloon filled with air sinks to the ground. That's because compressed air is heavier than its surroundings, so the air has mass or weight.Jul 30, 2019

How many pounds of air are in a cubic foot of water?

also one cubic ft holds .075 lbs of air at standard day

One cubic foot of air does not hold . 075 lbs. One cubic foot of air weighs . 075 pounds.Sep 3, 2004

How many cubic feet are in a compressed gas cylinder?

A typical cylinder, about 5′ tall, can hold about 230 cubic feet of nitrogen gas, if it is filled to the maximum operating pressure – which can be in the range of 2,200 psi, that is to say, if it is full.

What is the weight of 1 liter of air?

1.293 grams

A litre of air weights 1.293 grams at NTP.

How much does a cubic foot of water weigh?

The specific weight of water is 62.43 pounds (avoirdupois) per cubic foot. 62.43 pounds * 16 ounces = 998.88 ounces.Mar 15, 2017

How many molecules are in 22.4 liters of gas?

There is a neat property that applies to any gas that a 22.4 liters of it at STP (standard temperature and pressure) contains 6.02214199 x10^23 molecules of said gas. This amount (Avogadro's number) is called a mole. So another way to say this is that a singe mole of gas at STP will fill 22.4 liters.

How many liters of gas does a singe mole of gas at STP fill?

So another way to say this is that a singe mole of gas at STP will fill 22.4 liters. The special thing about a mole is that a if we have a molecule, we can find that molecule's molecular weight (from a periodic table) and that's how many grams a mole of the molecule would weigh.

Is air a composite mixture?

This one doesn't have an answer that is exact or necessarily correct as air is a composite mixture of various gases and this mixture can change due to an enormous quantity of variables. Discussing these variables and how these variables affect the air is one of the foundations of meteorology - the study of weather.

How to measure weight drop in scuba tank?

You could take that scuba tank, filled, and put it on a good scale. Open the valve a crack, let the air out slowly, and watch the weight drop. If it's say a 3 L tank filled to about 200 atm, you could see roughly a 1 kg drop, which should be easy to measure even if the tank weighs 10 kg or more.

How many milligrams of mercury is in 20C?

My CRC Handbook of Chemistry and Physics gives the density of dry air at 20C at 760 mm of mercury (one atmosphere of pressure) to be 1.204 milligrams per cubic centimeter. I'll leave it to you to convert to pounds and cubic feet. The density of air depends on pressure and humidity.

Can you weigh two heavy metal containers?

You could take two equally heavy metal containers (check with a balance, and you can add small weights on one side if they aren't equally heavy). You can measure their weight difference on a balance (again, by adding weights to one side until they balance out), when one container has air in it and the other has a vacuum. But then the tricky part is getting a vacuum in one of the containers.

Can you weigh a balloon on a scale?

But be very careful about this! If you fill a container (ball, balloon) with air and put it on a scale, you are measuring the weight of the ball plus the weight of the air, *minus* the weight of the volume of air that's displaced by the inflated ball (this is the buoyant force). The buoyant force is quite noticeable if you put helium in a balloon, because the total weight of the helium plus the balloon minus the buoyant force can be negative.
