70 m^3 of air flows in an intake airway towards a working section. Before entering the working section 10 m^3/s is drawn off and passed through a filter leaving with a dust concentration of 120p/ml. 50 m^3 is passed through a bulk air cooler leaving with a dust concentration of 100 p/ml. After the remixing of the air streams and before the air enters the working section,the dust count of the mixture is 130p/ml. Calculate the dust concentration of the original 70 m^3/s.

A control, process for a glass furnace will remove boron from the 1400 oF furnace by cooling the exhaust to 275 oF in an evaporative cooler to condense B2O3. The cooled exhaust will then pass through a ro verse-jet filter to remove suspended dust, including the B2O3 particulates. Draw a preliminary flow sheet for the process, indicating any auxiliary equipment needed, List any operating difficulties you think might arise with this system.
show complete solution. A modified atmosphere requires higher-than-normal amounts of oxygen but sparing amounts of water vapor. You have two streams available for mixing: stream A is dry air (79% N2, 21% O2) stream B is enriched air saturated with water vapor (2.74% water vapor, 65.65% O2, and the balance is N2) The desired product should contain 0.74% water vapor. Determine the oxygen content (mole fraction) of the product stream.
A large rank contains 100 gal of brine in which 10 lb of salt is dissolved. Brine containing 0.2 lb of salt to the gallon runs into the tank at the rate of 6 gal/min.

Industrial representatives claim that the ambient air quality standard for SO, is so low that one exceeds it if one strikes a simple wooden match in a modest-sized room. Is this true? (a) Calculate the concentration expected for striking such a match in a room that is 15' x 15' x 8'. A typical 2-inch wooden match contains, approximately, 2.5 mg of S. (b) Compare the resulting concentration to the annual average SO, ambient air quality standard.
