A convective kerosene heater is tested in a well-mixed 60 m3 chamber having an air exchange rate of 0.3 ach. After one hour of operation, the nitric oxide (NO) concentration reached 3 ppm.
Treating NO as a conservative pollutant, estimate the NO source strenght of the heater (in mg/hr).
Assume: 25 oC and 1 atm
