Robert Fogt. The N stands for Normal. It means it was measured at standard temperature and pressure. Because the volume of gasses change with temperature or pressure, it is necessary to specify the temperature and pressure the flow rate was measured at.

Standard pressure is 1 atmosphere. In the case of air compressors, I do not think it will matter much. Flag 1 like. Comment Post Cancel. N is metric normal temperature and pressure S is standard temperature and pressure I do not know if they differ at all. So M3 is the meter cube of volume occupied by the matter at given temperature and pressure. This measurement of volume is very important in fluid dynamics and aerodynamics to design proper designs of pipes, nozzles, airplane wings and many other industrial products that have to work in extreme temperature and pressure conditions.

Gas used is C3h8. Thank you for the explanation. Now I more understand the differences between Nm3 and m3. Its all depend on the gas working condition. Share This! You may also like. Standard Temperature and Pressure Conditions.
