Compressed Gas

[Terry G]

Is there a formula that would calculate how many cubic feet of natural gas would be in a gallon size tank at a certain pressure and temperature. For example 1 gallon tank, 2400 psi pressure at a temperature of 60F.

Find the btu's of energy per cubic ft then convert to gallons. Figure how many atmospheres of pressure in the tank and multiply.

Boyle's law is used to predict the result of introducing a change, in volume and pressure only, to the initial state of a fixed quantity of gas. The before and after volumes and pressures of the fixed amount of gas, where the before and after temperatures are the same (heating or cooling will be required to meet this condition), are related by the equation:

P1V1=P2V2

Here P1 and V1 represent the original pressure and volume, respectively, and P2 and V2 represent the second pressure and volume.

2400 x 1 = 14.7 x X

X = 163.3 gallons

Thank you for the answers , I finally understand it now. Been thinking on this one for awhile. Should have come here earlier.

Jessie,
Not sure exactly what you are asking. The question here was simple, because the temp didn't change. It's a whole different ball game when you compress a gas real fast, isothermal compression, adiabatic compression, monoatomic or diatomic gas. The equations are different for each. I put those books away 8 years ago and never want to open them again.
