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
