A room has a volume of 200m3 and the ventilation rate is 3 air changes per hour. Given the total CO2 generation rate is 5 L/min. Suppose occupants all arrived at the room together and the initial CO2 concentration was at the ambient (outdoor) concentration of 400 ppm. Calculate the indoor CO2 concentration one hour after the occupants arrived for the room

Many houses in the Washington area experience indoor air pollution by radon. A house of a volume V = 300 m3 has air leaking in from the soil with a radon concentration of 5000 pCi/L and rate of 20 L/h. During the winter time, the average rate of fresh radon-free air entering the house is only 400 L/h. Radon undergoes decay following a first order reaction with a rate constant k = 0.18/day. The house can be approximated as a...

A 70 year-old patient, Nick O'Steen, arrived at the hospital emergency room in worse shape than usual. His history included multiple hospital admissions over the past several years for illness associated with his 2 pack a day smoking habit which he started as an 18 year old in the United States Army. No one knew the dangers of smoking in 1956 when many young men picked up the habit and Nick often wished he had never started. On this admission...
