Question

Please do not post if you have not tested the code. Problem I need help with: The annealing process in reference problem is to be accelerated by increasing the temperature of the combustion gases inside the furnace. Consider three combustion gas temperatures, T = 700, 850, 1000 oC. Write a MATLAB program that: c. Calculates the speed at which the strip must move through the furnace for each T and displays this information to the command window. d. Plots the strip temperature as a function of time over the range 300 oC ≤ T ≤ 600 oC. All three curves should be on a single plot with a legend to show T for each case. Reference problem: A steel strip of thickness δ = 12 mm is annealed by passing it through a large furnace filled with combustion gases flowing through at a velocity of 0.5 m/sec. The strip is to be heated from 300oC to 600oC. Its properties are ρ = 7900 kg/m3, c = 640 J/kg/K, and k = 30 W/m/K. For a uniform convection coefficient of h = 100 W/m2/K and T = 700 oC, determine: a. The time required to heat the strip. b. How long must the furnace be for this process?
