A 0.6 m thick plate's temperature distribution is being estimated using finite difference methods. Initial temperature distribution is uniform at 30 C. A 70 C medium submerges the plate on both sides. The medum has a heat transfer coeffficient (h) = 50 W/m2K. The thermal diffusivity of the plate material is 2.7 x 10-4 m2/s., and the thermal conductivity (k) = 0.34 W/m K.

What are the proper values of M, N, Δx and Δt used in the finite difference solution? Write the finite difference expressions when estimating the temperature distribution history of the plate

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.
