What is the difference between Nm3 and m3?

Updated: 5/28/2024

NM3:

NM3 stands for Normal meter cube and especially this unit is used gas/vapour application. NM3 is a constant value under the Varying Pressure and Temperature.

NM3 is calculated if the Density and Mass of the gas/vapour is known.

For Eg : In a pipeline, If Air is flowing at the rate of 1000M3/hr at the Pressure of 5Barg and at the temperature of 30degC, then Density of Air can be arrived from the corresponding pressure and temp which is 6.9Kg/m3. Then Mass flow rate of Air will be obtained by multiplying the arrived density with the Volumetric Flow rate i.e Rho X V = 6.9X1000=6900Kgs/Hr.

Normal Flow rate of Air = Mass Flow rate / (Mol.wt of Air / 22.4) = 5349 Nm3/Hr

M3:

M3 stands for Metre cube and this unit is used in Solid, Liquid and gas application. Meter cube is used to quantify the matter in Volume.

In the above mentioned example, Flow rate of Air is mentioned as 1000M3/hr which is the Volumetric Unit.

Nm3 refers to normal cubic meters, which is a gas volume measurement at standard temperature and pressure conditions. On the other hand, m3 refers to cubic meters, which is a general volume measurement without specifying the temperature and pressure conditions. The difference lies in the fact that Nm3 takes into account the standard conditions for comparing gas volumes.

What is the difference between Am3 pr hr and Nm3 per hr?

Am3 refers to actual cubic meters, which accounts for the actual volume of gas being measured, while Nm3 refers to normal cubic meters, which adjusts for changes in temperature and pressure. Therefore, the difference between Am3 per hr and Nm3 per hr lies in the way the gas volume is measured and corrected for varying conditions.

What the difference between nm3 and sm3 of gas flow?

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.

What is the relationship between m3 and cm3?

1 cubic meter (m3) is equal to 1,000,000 cubic centimeters (cm3). This is because 1 meter is equal to 100 centimeters, and when cubed, this results in a difference of 1,000,000 between the volumes in cubic meters and cubic centimeters.

What is the difference between Nm3 and Sm3?

Nm3 refers to gas measured at standard conditions of 0 degrees Celsius and 1 atmosphere pressure, while Sm3 refers to gas measured at standard conditions specific to the gas composition being measured. Sm3 takes into account the actual molar composition of the gas, making it more accurate for gas mixtures other than pure nitrogen.

Is 1.50 cm3 greater than less than or equal to 1.50 x 103 nm3?

Both recalculated in SI-units for volume m3 will give the first one is greater:1.50 cm3 = 1.50*10-6 m31.50*10+3 nm3 = 1.50*10+3([nm]3) / ([109nm/m])3 = 1.50*10+3 * (10-27) [m3] = 1.50*10-24m3Keep in mind that 1 nm = 1*10-9 m,so when cubed, symbolised by [.]3 , it gives:[1 nm]3 = [1*10-9 m]3 = 1*10-27 m3 = 1 nm3 (!!)

How do you convert Kg to Nm3?

Kilograms (Kg) and cubic meters (m3) are different units, representing mass and volume, respectively. To convert Kg to Nm3 (normal cubic meters, a unit used for gases), you would need to know the density of the substance in question. The conversion involves multiplying the mass in Kg by the inverse of the substance's density in Kg/m3.

How do you convert NM3 in to metric ton?

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).
