Question 2 4 Points An Aerospace Company Manufactures Titanium Spheres That Need To Be Sintered To A Temperature Of 85 1 (43.85 KiB) Viewed 25 times

Question 2 (4 Points) An aerospace company manufactures titanium spheres that need to be sintered to a temperature of 850K after processing. Hot combustion gas at 1500K is used to heat the titanium spheres with a diameter of 0.2m. The spheres are initially at a temperature of 305K. Calculate the time that is needed for the spheres to reach 850K. Be sure to show that you have verified your method is valid. T.: 1500K h: 50 W/m2/K Ø: 0.2m Extra Credit Question (1 pt) If the shape of the titanium was changed to a cube that the sphere in Question 2 inscribes, (fits into) how would that effect the cooling time? Justify your answer.
