Why is important to understand Basic Driving Maneuvers. Compare and contrast making a midblock U-turn and a three-point turnabout. Which stages of the turnabout are the most dangerous? Which stages would cause you to be at fault if your car were hit by an approaching vehicle? Ask your parents/guardians their thoughts on this subject. Write a short (one- to two-page) review. Be sure to include the thoughts/opinions of your family member(s).

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
