I know what you're saying, the figure I got was from the Control of Substances Hazardous to Health (COSHH) as a maximum allowable over 10 mins. As I said before I'm only a first year student designing a ventilation system for a college project, so my understanding of things is probably a bit...
Hi all,
I'm trying to calculate if my fresh air supply rates are sufficient to ensure CO levels don't exceed 300 ppm over ten minutes, but I am unable to find a suitable value for q = the rate of contaminant release in L/s. Would any of you nice people be able to help me out.
Also excuse me...
