Researchers collected data to examine the relationship between pollutants and preterm births in Southern California. During the study air pollution levels were measured by air quality monitoring stations. Specifically, levels of carbon monoxide were recorded in parts per million, nitrogen dioxide and ozone in parts per hundred million, and coarse particulate matter PM1o in ug/m3. Length of gestation data were collected...

Problem 2 A brass tube of inner and outer diameters D,-2 cm and Do-3 cm, respectively, is used to transfer heat from ambient air flowing across the tube to cold refrigerant (R-22) flowing inside the tube. The ambient air is flowing at un-0.1 m/s, and To 30°C. The cold refrigerant flow rate is m 1 gs, and its mean temperature is Tm-20°C. (a) Find the overall heat transfer coefficient, UA (b) To enhance the heat transfer, 16 straight fins of...
