Dear all;
I need to calculate PM10 as g/second from it concentration in ppm for a stack.
The PM10 concentration is 150 ppm.
Q is 9 m3/s.
Temperature is 120 C.
Is there any formula to do this?
Sincerely
The first question back is the definition of [ppm] in the context of particles. Is it mg/kg or ml/m3 (ratio of mass or volume)? Either way you need a specific density of the particles. The density can probably be estimated/determined if you know the source of the particles.

Mr. Riess is correct in that the meaning of ppm for particulate matter is not specific. In over 45 years in the field, I've not seen the particulate matter concentration expressed as such. It is more usually expressed as milligrams per cubic meter, or pounds per cubic foot, or grains per cubic foot. In some rare cases, number of particles per cubic foot or cubic meter. In any case, no matter how the concentration is expressed, you would also need the stack gas flow rate, in volumetric or mass units, to use the concentration and turn it into a mass emission rate of g/s.
