Person breathes out at the rate 0.3 L/min = 60s0.3L=0.005L/s for 6 person CO2 expels
out = 6×0.005=0.030sL
The concentration of CO2 is 400 ppm and it has to maintain upto 1000 ppm.
AT STP volume of CO2 is 22.4 L which is equal to 1 mole = 44 g
so mass of CO2 expells out = 0.03×44=1.32g /s
400ppm means 400 g of CO2 present in 1000000 particles of air
concentration of incoming air = 400×22.444=98.3Lg
six person breaths out = 600.3×6×22.444=0.059g/s
s per the standards
air flows= Co35.3+98.3Q
