a power plant 55 kg of fly ash per hour up the stack. the flow rate of the hot gases in the stack is 1.0 m^3/s. what is the concentration of the fly ash in micrograms per cubic meter?
Amount of fly ash in µg/m3:
(55 kg / 1 hr) × (1×109 µg / 1 kg) × (1 hr / 3600 sec) × (1 sec / 1.0 m3) = 1.53×107 µg/m3
Answer: The concentration of the fly ash is 1.53×107 µg/m3
