An industrial company manufactures tungsten cubes that need to be sintered to a temperature of 80OK after processing. Hot combustion gas at 100OK is used to heat the tungsten cubes with a side length of 0.3m. The cube is initially at a temperature of 298K. Calculate the time that is needed for the cube to reach 800K. Be sure to show that you have verified your method is valid. 0.3m T: 1000K h: 100 W/m²/K

Metal spheres, 10 mm in diameter, are to be annealed by heating them to 827°C then allowing them to cool slowly in air at 27°C to the point where they are in thermal equilibrium with the air. 2000 balls are annealed in one hour’s time. What is the total rate of their heat transfer if they are made of steel, lead, or copper? a.Sketch the problem. b.Draw lines identifying the control volume, or control mass. c.Identify the states with numbers, letters, or descriptions such as “in” and “out”. d.Write down the knowns and unknowns. e.Identify what is being asked for. f.State all assumptions.
After going through the production process, thin plates with a length of 0.5m are cooled by suspending them vertically in a room with still air at 35°C. To maximize production throughput, the plates are hung as close together as possible. There is a concern however, that if the plates are too close together, the cooling will take longer, costing the company additional money. If the plates are initially at a temperature of 75°C, please answer the following: 1. What is the minimum plate spacing that would avoid interference between their free convection boundary layers? 2. What is the velocity in the x-direction at the upper edge of the plate?
Brittle Dune Buggy Parts A mechanic who was building a lightweight dune buggy needed some high-strength aluminum parts. Since he had access to a heat-treating furnace, he decided to do the solution heat-treating and aging process himself. He obtained 2024 aluminum bars and made the parts. Then her heat treated the part in a furnace to 1200 deg F., quenched them, and allowed them to age naturally. He noticed they had small blisters over their surfaces and when he began to hammer one in place, it broke in two places. What did he do wrong? Could the parts be salvaged in any way?
An electrical resistance wire made of tungsten dissipates heat to the surroundings at a constant rate. Which of the following equations are you going to use to compute for the temperature at any point within the wire when the temperature throughout the whole wire no longer changes with time? Assume that the wire can be approximated as a thin cylinder. a. Fourier-Biot equation b. Poisson equation c. Diffusion equation d. Laplace equation
Refer to Table 3.2 in the lecture and take the data for air, water (steam), and four other gases listed in the table. Plot the data in a graph with the thermal conductivity on the vertical axis and the temperature range from 200 K to 600 K on the horizontal axis. Use colors or different dashed lines to make the graph presentable and understandable. The graph should look like the graph in Figure 3.1 in the lecture. Provide a short explanation of the graph in three to five sentences.
