How do you convert between the two units? Please help. Thank you. Unfortunately neither Nm3 or Sm3 or Standard cubic feet for that matter are complete definitions in themselves.

It is essential to know the temperature and pressure conditions that the author believed were "Normal" or "Standard". Once you have the temperature and pressure references it is a simple matter to do the conversion.

Messrs tickle and katmar are both right. Notwithstanding their expertise, they should clearly indicate T and P to enable making conversions to differing T or P values. I had one experience where there was a dispute on the amount of hydrogen exported to another plant from one plant in an integrated petrochemical complex.

It turns out that one plant was designed by a European company and the other was designed by a Japanese company. This led to inconsistent basis for calculating the mass of hydrogen transferred from one plant to the other. Looking back at your university text books may not help either in this case. You must refer to the design basis of your respective plants. Just to make your life easier: an extensive thread on this topic can be found on Thread The standard conditions are as follows: Temp.

Homayun, Those may be your definitions of Standard and Normal but there are many others. No katmar, These are to my knowledge the widely used conditions, I haven't invented them! 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.

The standard temperature and pressure differs between industries, and it may be that Normal and Standard use the same temperature for your industry. If standard and normal do use different temperatures, then the relationship would be according to the ideal gas law.

As the characteristics of the compressor correspond to standard conditions, you have to take care that X flow at pressure conditions correspond to Y flow at normal conditions. Vacuum Engineer. It therefore it got bigger Then you squeezed it at a higher pressure It shrank Just remember to convert using the absolute Temperatures and Pressures and you can't go wrong.

But I guess in your question "N" means Newton. A power consumption has generally not the same meaning than a flow. But I will try to answer your question anyway : The first thing you have to do to convert an unit into another is to mind in international unit.
