I think this is a bit of a chemical engineering question, can anyone help?

Let's say a 1L bottle of DMF was knocked over in a 1.1m wide, 1m deep and 1.3 m high fumehood with a face velocity of 0.5 m/s and the sash at 0.5 m height.

Assuming the spill covered the whole base of the fumehood, what would the concentration be (in ppm) of DMF vapour inside the fumehood atmosphere?

Assume the temperature is 20 Celsius.

Thanks!
