A 2,000-foot, one-way, two-lane rectangular tunnel filled with cars is blocked by an accident at the exit. The longitudinal ventilation system involves large exhaust fans drawing ambient air into one end of the tunnel and blowing it out the other end Assume that the tunnel fills with cars, all with engines idling. One car occupies 18 linear feet of space in one lane in the tunnel and emits 2.6 grams of CO per minute with the engine idling. The tunnel is 30 feet wide and 15 feet tall. The fans blow 270,000 ft^3 /min of ambient air into the tunnel entrance. Derive an equation to predict the steady-state concentration of CO as a function of position in the tunnel. The CO concentration at 971 ft away from the entrance is 38mg/m^3.
Required:
What is the concentration of CO in ambient air?

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
