A slab of meat 25.4 mm thick originally at a uniform temperature of 10°C is to be cooked from both sides until the center reach 121°C in an oven at 177°C. The convection coefficient can be assumed constant at 25.6 W/m2.K. Neglect any latent heat changes and calculate the time required. The thermal conductivity is 0.69 W/m².K and the thermal diffusivity is 5.85x10-4 m²/h.

An aluminum transmission line with a diameter of 20 mm has an electrical resistance of R'elec= 2.636 × 10-4 Ω/m and carries a current of 700 A. The line is subjected to frequent and severe cross winds, increasing the probability of contact between adjacent lines, thereby causing sparks and creating a potential fire hazard for nearby vegetation. The remedy is to insulate the line, but with the adverse effect of increasing the conductor operating temperature. (a) Calculate the conductor temperature...
