Question

An unvented, portable heater fueled with kerosene is tested under controlled laboratory conditions. After running the heater for two hours in a test chamber with 46.0 m3 volume and ventilation rate of 11.5 m3/h, the concentration of carbon monoxide (CO) reaches 20 mg/m3. The initial CO concentration in the lab is zero, and the ambient CO level is negligible throughout the test.

a. Find the rate at which the heater emits CO.

b. If the heater is used in a small home to heat 120 m3 of space at a ventilation rate of 48 m3/h, calculate the steady state CO concentration.
