1 US gallon = 0.133680556 cubic foot (Google) (80 gallon)*(0.133680556 cubic foot/gallon) = 10.69444448 cubic feet The current pressure is meaningless as to the volume of the tank. If you have the temperatrue and pressure of the tank, you can determine the mass and hence density of the air inside the tank, and also determine how many cubic feet of air you have if you were to release the pressure into another fixed volume. The temperature is a tricky one though. If you pump the tank up, the air inside the compressor is hotter than ambient. This is due to the compressor adding internal energy and the conservation of energy principles. The air has a quantity of energy to it, capturing a large volume and reducing the volume (compressing) puts all that energy into a smaller container. More energy per mass means hotter gas. The gas will eventually cool to ambient, and lower the tank pressure slightly. Point being, when you release the gas at a cooled stage, the air re-expands and drops temperature due to the conservation of energy (the inverse of before). In essence this is how AC works. The conversion of energy and all that good stuff like entrophy makes it a challenge, so here'e what I think your asking, in a nut shell. If you released all the air into a giant balloon or something, the general equation, and I mean very very general, P1V1 = P2V2 V2 = P1V1/P2 P1 = 175 PSIG + 14.1 PSI = 189.1 PSIA P2 = 14.1 PSIA V1 = 10.69444 ft^3 V2 = 189.1/14.1*10.69444 = 143.426 ft^3143.426/.133680556 = 1072.903 gallons of Air in its released state at standandard pressure. Again, this is assuming an adiabatic isentrophic process. It is only a vague estimation. Chris Morrison Aero Student OSU

How much does 100 cubic feet of air weigh?
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.
How many gallons of air do you breathe in a year?
600
What size portable air conditioner is needed for a room of 1500 cubic feet?
You will need a portable air conditioner that offers 24,000 - 25,500 BTUs to cool a room of about 1500 cubic feet. This is a large sized room and a 2.5 ton unit would cool that area.
What organ helps you breathe the 282 cubic feet of air you need everyday?
Your diaphragm helps you breathe the air you need every day.
How many gallons are in 40 pounds?
All depends. Are we talking US gallons or UK gallons (they are different). Also, it matters what we are talking about, 40lb of water, molasses or engine oil of a specific gravity. Gallons at one time were different for dry goods and liquids. The US gallon for liquids is 231 cubic inches and was the old UK wine or Queen Anne gallon. The UK gallon was standardized in 1824 so the same value was used for liquids and dry goods. This Imperial gallon was set at 277.42 cubic inches as this was the capacity of exactly 10lb of pure water at 62F. If you want a numeric value for either gallon, see www.footrule.com .
How many uk gallons in 2 feet SQ fish tank?
Zero. For a tank to be able to hold anything, even water or air, it must be three dimensional, measured as cubic feet However, for 2 cubic feet, there are about 6.23 UK gallons in 1 cubic foot, hence about 12.45 UK gallons in 2 cubic feet.
How many gallons of water are in 226 cubic feet?
226 cubic feet of space = 1,690.6 gallons of space (rounded) even of there's no water in it. It could be full of air, maple syrup, or motor oil, or it could be completely empty. It's still 1,690.6 gallons of space.
How many cubic feet of air in a 12 inch diameter pipe 10 feet long?
7.854 cubic feet.
How many cubic inches is in a 25 gallon air tank?
5,775 cubic inches in 25 US gallons.
How much air is used to combust a gallon of gasoline?
It takes 1200 cubic feet of air or 8977 gallons of air to combust one gallon of gasoline.
How many cubic feet of air makes 1 liter of air?
1 liter of air is equivalent to approximately 0.0353 cubic feet of air.
.197 cubic liters of air equals how many cubic feet of air?
A liter is always a cubic measurement, so that adjective in unnecessary. 0.197 liters are 0.006956989344 cubic feet, no matter what you are measuring.
How many gallons of air are in one cfm?
There is not a direct relationship between gallons and cubic feet in this context, as air volume is measured in cubic feet per minute (cfm) rather than gallons. The volume of air in one cfm would be equivalent to the volume of a cube that is 1 foot by 1 foot by 1 foot.
What is the volume of a 55 gallon drum in cubic feet?
About 7.352 cubic feet.
How many cu ft of nitrogen are in a liter of nitrogen?
The liquid nitrogen itself is irrelevant. The answer would be the same if you asked about gallons of orange juice, phoenix tears, or rat faeces. One cubic meter is approximately 264.172052 gallons.
