Explain what Sam can do to fix his engine in the following scenario. Situation: Sam tried out a new hobby and rebuilt a car from scratch. When he got to the crankshaft, he was careful to attach it to the camshaft with
the gears. He also made sure that the pistons were tightly attached to the crankshaft gears as well. It was also held in place by a series of journals.
Finally, he made sure that the belt was in place on one side of the crankshaft. When James came over to look at the car, he noticed that Sam's
crankshaft was still incomplete.

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.
