A gas engine has been running in a closed garage, resulting in a CO level of 600ppm. Upon opening the door, turbulent mixing begins.?

Update:

A gas engine has been running in a closed garage, resulting in a CO level of 600ppm. Upon opening the door, turbulent mixing begins. If the door is 3m wide and 2m high, the garage is 10m long, and eddy diffusivity is approximated to be 1m2/s, how long will it be before CO concentration has dropped to a level of 100ppm, which is considered safe for brief exposure periods?
