Acopper alloy cylinder that is 1.3 feet long with a diameter of 41.30 inch is subjected to a tensile stress of 1035 psi along its length.

assuming this applied stress is purely elastic, calculate the diameter, in inches, of the cylinder under this load.

for this alloy, the elastic modulus is 961136 psi and the poisson's ratio is 0.33.

answer format x. xx

unit: inches

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.
