Obtaining the airflow knowing the diameter and the air speed

• Move the ‘D’ marker on the diameter bar or introduce the desired value into the corresponding cell.
• Move the bar or introduce the value for ‘air speed’
• The corresponding airflow will show in the lower cell

Obtaining air Speed knowing the diameter and the airflow

• Set the diameter by moving ‘D’ marker on the bar or introducing the desired value into the corresponding cell.
• Set the airflow by moving the marker on the bar or introducing the acknowledged value.
• The corresponding air speed will show in the lower cell

Obtaining diameter knowing the airflow and the air Speed

• Move the ‘airflow’ marker on the bar or introduce the desired value into the corresponding cell
• Move the bar or introduce the value for ‘air speed’
• The corresponding diameter will show in the lower cell

Determining the dynamic pressure

• Move the ‘air speed’ marker on the bar or introduce the desired value into the corresponding cell
• The corresponding dynamic pressure will show in the lower cell
