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.
