At a recent university football game, a terrorist group decided to do a study in which they flew a crop duster over the stadium and dusted the western side of the stands with anthrax spores then waited to see who developed disease. fortunately, the wind was blowing toward the west, reducing the number of people who had a direct exposure. the fans were followed medically over the next 6 months. a total of 100 people who sat on the eastern side developed disease and 1000 people who sat on the western side developed disease. of the 100,000 people in attendance, 50,000 were sitting on the western side of the stadium and were considered to have been exposed.
calculate the odds ratio and interpret your results.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
