A square steel plate is at the 400 C in the beginning. Then the plate is placed in a 10 C environment. Edge length of the square is 2 cm. Governing equation of the temperature distribution is as follows: VT = 6.6 T t By using FTCS and Crank-Nicholson method, generate proper computer programs in order to; a- Determine the temperature distribution on the plate after 4 seconds. b- Specify when the temperature at middle point of the plate becomes equal to the 15 C with the precision of 0.1 C. Take Ax = Ay = 0.1 cm and specify the At by yourself. A square steel plate is at the 400 C in the beginning. Then the plate is placed in a 10 C environment. Edge length of the square is 2 cm.
