What is the CV of natural gas?
What is the CV of natural gas?
The CV refers to the amount of energy released when a known volume of gas is completely combusted under specified conditions. The CV of gas, which is dry, gross and measured at standard conditions of temperature (15oC) and pressure (1013.25 millibars), is usually quoted in megajoules per cubic metre (MJ/m3).

How strong is 520 m3?
The newly-discovered species of Madagascan spider known as Darwin’s bark spider (Caerostris darwini) weaves the strongest known spider silk with a tensile strength of up to 520 MJ/m3 (megajoules per cubic metre) – twice as tough as any previously described silk.
Is MJ megajoules?
A megajoule is a unit of energy in the International System of Units (SI). The symbol for megajoule is MJ. The base unit for a megajoule is joule and the prefix is mega. Mega denotes a factor of a million (106) which means that there are 1,000,000 joules in a megajoule.
How do you convert m3 to MJ?
To do this:Take a meter read at a set time on a typical day.Take another read the next day at the same time.Then translate the difference between the two meter reads into megajoules by multiplying the figure by either: 38.61 if your meter records cubic meters; or. 1.09 if your meter records cubic feet.
How many MJ are in a natural gas m3?
How many kg is a cubic meter of gas?
What is normal cubic meter of gas?
The two common standardized volumes are standard cubic feet (scf) and normal cubic meters (Nm3). A standard cubic foot of gas corresponds to 1 cubic foot of gas at 32 °F (0 °C) and 14.6959 PSI, and a normal cubic meter of gas corresponds to 1 cubic meter at 20°C at 101.325 kPa (NIST Reference).
How do you calculate cubic meters of gas?
Imperial gas metersTake a meter reading.Subtract the new meter reading from the previous reading to work out the volume of gas used.Convert from cubic feet to cubic meters by multiplying by 0.0283 OR dividing by 35.315.Multiply by the volume correction factor (1.02264).Multiply by calorific value (40.0).
What is a unit of gas?
Units of gas measure the amount of gas consumed at a property. 1 unit of gas is equal to one kilowatt hour (kWh) of gas used.
What is difference between nm3 and m3?
M3 is the Meter cube and NM3 is Normal Meter cube. NM3 is the value that a matter whether solid, liquid or gas of a constant mass occupies under normal or standard conditions and M3 is volume that it will occupy at the prevailing conditions of temperature and pressure.
What is normal condition for gas?
Normal conditions refers to gas volumes measured at 0°C and 101.325 kPa (760 mm Hg), often abbreviated to NTP (Normal Temperature and Pressure).
What does normal m3 mean?
Normal Cubic Meter or “Nm3” shall mean the quantity of Natural Gas which, when absolutely dry, at a temperature of zero degrees Celsius (0° C) and at an absolute pressure of one decimal zero one three two five (1.01325) bar, occupies the volume of one (1) cubic meter.
