Introduction
The here provided tools are indicative only and it does not substitute a proper engineering approach. NTT cannot be held liable for any results derived by this online converter.
The toolbox is structured in two types.
- Translation modules - translates within the same system, e.g. metric/ metric or imperial/ imperial
- Conversion modules - convertes between systems, e.g. metric/ imperial or vice sersa
The toolbox should ease your work in the area of designing aeration plants, utilizing air compressors.
Metric System
| Actual Airflow | [m3/h] | defined at given p0barometric pressure [bar], T1 air temperature [°C], rH relative humidity [%] |
| Norm Airflow | [Nm3/h] | defined at: 1.013 bar barometric pressure, 0°C, 0% relative humidity |
| Standard Airflow | [Sm3/h] | defined at: 1.013 bar barometric pressure, 20°C, 36% relative humidity |
Imperial System
| Actual Airflow | [acfm] | defined at given p0 barometric pressure [psi], T1 air temperature [°F], rH relative humidity [%] |
| Standard Airflow | [scfm] | defined at: 14.7 psi barometric pressure, 68°F, 36% relative humidity |
