You could use the following Rule of Thumb: Multiply the square of the inside diameter, in inches, by the gauge pressure, in psi; multiply this by 0.372; the answer is the approximate number of cubic ft of gas (standard conditions) in 1,000 ft of line, e.g 7 inch ID pipeline, 8km long, operating at 65 barg:
8 km = 26246 ft = 26.246 kft
65 Bar = 942.7 psi
so, 7 x 7 x 942.7 x 0.372 = 17183.5356 scf / 1000 ft of line, so total gas in 26246 ft of line = 17183.5356x26.246=450999.0753576 = 0.45 MMSCF of gas.
Or, you could use, Pv=znRT, assume a z of, say 0.9 , lets say the pipeline is at 6 deg (normal temperature for a shutin subsea pipeline in the North Sea)
65x (Pi x 0.1778 x 0.1778 x 8000/4) = 0.9 x n x 8.314x10-5)x (273+6)
n = 618523 moles
1 kmol of a gas occupies 22.441 Nm3 at standard conditions
t.f 618.523 kmol should ocupy 618.523 x 22.441 = 13880.274643 Nm3.
1 Nm3 = 37.326 SCF, therefore, 13880.274 Nm3 = 518095.131324618 SCF = 0.52 MMSCF.(Nm3 to SCF conversion seems to have different factors, I've seen it range from 34.89 to 38.9!!!).
Not very far from the 0.45 the rule of thumb calculated!!!. It should be noted that the standard volume is independent of the particular gas in the pipeline, so we don't need to knwo the MW or density. Any gas at a given P&T will have the same number of moles (and hence standard cubic feet), the actual mass in kg will ofcourse depend on the molecular weight. Riz
If you mean standard or normal volume, in case the pressure is considerably higher than the atmospheric value, you need to use an expression for the compressibility factor or take it from a table, depending on the values of pressure and temperature in the pipeline. You can then use a state equation for the gas (knowing its molecular mass), from which you'll be able to calculate its density at working conditions. By multiplying the density by the physical volume of the pipeline pi*D^2/4*L (L=length, D=diameter) you obtain the mass of gas, which divided by the standard or normal density gives you the desired volume.
Use Boyle's law
The Lower Explosive Limit (LEL) of natural gas (which is primarily methane). is 5% by volume in air. The Upper Explosive Limit (UEL) is 15% by volume in air
You need the inside radius (1/2 the inside diameter) of the pipe and the pipe's length. Then, use this formula:Volume = Pi x r2 x length
Using information about a force to calculate the resulting acceleration..Using the change in the volume of a gas to calculate the change in its pressure.
100 MSDCF stands for 100 million standard cubic feet. It is a unit of measurement commonly used in the oil and gas industry to quantify the volume of natural gas. "Standard" refers to the conditions under which the gas volume is measured, typically at a standard temperature and pressure. This unit helps in assessing production, reserves, and consumption of natural gas.
To calculate the volume of biogas in a pipeline, you need to know the pipeline's dimensions (length and diameter) and the pressure and temperature of the gas inside. Use the ideal gas law equation, PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature. Solve for V to find the volume of biogas in the pipeline.
To calculate the quantity of nitrogen gas needed for purging a pipeline, you would first need to determine the volume of the pipeline. Once you have the volume, you can use the ideal gas law (PV = nRT) to calculate the amount of nitrogen gas required. Make sure to consider factors such as the desired flow rate, pressure, and temperature during the purging process.
It can be but that is no the only means by which it is distributed.
To calculate tidal volume (TV) from gas volume and respiratory rate (RR), you would divide the gas volume by the respiratory rate. The formula is TV = Gas Volume / RR. This calculation gives you the average volume of air moved in and out of the lungs with each breath.
The Southeast Region Natural Gas Pipeline Network appears to be the most prominent pipeline. It is located in the US and provides 39 states with the gas supplies they require.
No, it is not safe to burn brush next to a natural gas pipeline. The heat from the fire could potentially damage the pipeline, leading to a gas leak and posing a serious safety hazard. It is important to keep flammable materials away from pipelines to prevent accidents.
To calculate the volume of natural gas in standard cubic meter at standard pressure, you can use the ideal gas law equation: V = nRT/P, where V is the volume in standard cubic meters, n is the number of moles of gas, R is the ideal gas constant, T is the temperature in Kelvin, and P is the standard pressure. Given that standard pressure is typically defined as 1 atmosphere or 101.325 kPa, you can plug in these values along with the temperature and number of moles of gas to calculate the volume of natural gas in standard cubic meter at standard pressure.
Without knowing whether this is atmospheric-pressure natural gas, pipeline-pressure or compressed natural gas (and the pressure it's been compressed to), or liquefied natural gas, this is an unanswerable question.

Natural gas is typically moved through pipelines, which are underground tubes that transport the gas over long distances. Compressor stations are used to pressurize the gas and keep it flowing through the pipelines. In some cases, natural gas can also be transported via ships or trucks in the form of liquefied natural gas (LNG).
