LITERS PER MINUTE, AIR
1. DRAW A VERTICAL LINE FROM THE POINT THAT REPRESENTS THE AIR FLOW ON THE HORIZONTAL
AXIS UNTIL IT INTERSECTS A DIAGONAL LINE INDICATING THE REQUIRED VOLUME (%) OF CO2 FLOW; 2.
RUN A HORIZONTAL LINE TO THE VERTICAL AXIS TO FIND REQUIRED FLOW OF CO2 IN LITERS/MINUTE; 3.
TO OBTAIN THE AIR FLOW (IF CO2 FLOW IN LITERS/MINUTE AND % CO2 ARE KNOWN), REVERSE
PROCEDURE.
