E = (cs Qsd)/PK)
where:
E = emission rate of particulate matter, kg/Mg (1b/ton) of stone feed.
cs = concentration of particulate matter, g/dscm (gr/dscf).
Qsd = volumetric flow rate of effluent gas, dscm/hr (dscf/hr).
P = stone feed rate, Mg/hr (ton/hr).
K = conversion factor, 1000 g/kg (7000 gr/lb).
