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.
SI base units[9] Name Symbol Quantity metre m length kilogram kg mass second s time ampere A electric current kelvin K thermodynamic temperature mole mol amount of substance candela cd luminous intensity Candela is less used, but the other are very important.
