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.

The energy content of natural gas is typically measured in cubic feet (cf) in the United States and in cubic meters (Nm3) in other countries. One cubic foot of natural gas produces approximately 1,000 BTU (British Thermal Units) of energy. Therefore, 1 Nm3 of natural gas is roughly equivalent to 35,315 BTU.

To convert NM3 (normal cubic meters) to metric tons, you need to know the density of the gas. Once you have the density, you can multiply the volume in NM3 by the density to get the mass in metric tons. The formula is: Mass (metric ton) = Volume (NM3) x Density (metric ton/NM3).
1 kilogram of LPG is equivalent to approximately 1.96 normal cubic meters (Nm³) of LPG.
I don't know what does Nm3/h mean? Please help me. Thanks a lot!
You cannot convert kilograms per hour (kg/hr) into nanometers cubed per hour (nm3/hr). The kilogram is a measure of mass or weight while the cubic nanometer is a measure of volume. There is no direct conversion, unless you specify the density of the material involved.
Nm3 is a common unit used in industry to refer to gas emissions or exchange. It stands for Normal cubic meter. "Normal" is always dependant on the individual circumstances of each gas, pressure, and use. To convert Nm3 to a cubic foot of gas (under standard conditions), multiply by 38.04. Therefore, 1,000 Nm3/day = 1 kNm3/day = 38,040 cf/day.
There are 1,000,000,000,000 hm3 in 1 nm3 of natural gas.
Nm3 (normal cubic meters) and Sm3 (standard cubic meters) are units used to measure gas flow at different conditions. Nm3 is gas flow measured at standard temperature and pressure conditions, while Sm3 is gas flow measured at the actual flowing temperature and pressure conditions. The main difference is that Sm3 takes into account the variations in temperature and pressure, while Nm3 assumes standard conditions.

There is no conversion. Cubic feet is always cubic feet. Standard = normal. This is not true, standard cubic feet is a cubic feet of a substance (typically a gas) at 60 °F and 1 ATM pressure where as normal cubic feet would be the volume of a substance (again typically a gas) at 0 °C and 1 ATM pressure. It follows that to convert from one to another, an estimate can be made using the ideal gas equation. If you need any further instruction let me know. It's a secret, so write to him. It's not a secret Jens I just didn't want to extensively talk about the ideal gas law since lots of people already know about it.
