Design a heat equation model to determine the solution. The physical data needed to model for copper includes: density p= 5.82g / cm', thermal conductivity K = 0.095cal / cm sec C, specific heat O =0.097cal / g C. The initial temperature is 70sin(t x/100) C and the ends are kept at 0 C of a laterally insulated copper bar of 120 cm long. Determine the time its goint to take for the maximum temperature in the bar to drop to 100 C?
