Q$1)$ A can contains meat loaf, solidly packed, at $70C.$ The can is placed in an autoclave where it is heated with steam at $121C.$ What will be the temperature at the can center after $30$ minutes?

Assume that the temperature of the can surface is $121C$ from $t=0.$

Data:

Can dimensions: Diameter $=8cm,$ Height $=6cm$

Thermal diffusivity of the loaf $=0\mathrm{.}2{10}^{-6}\frac{m^2}{s}$

$=\frac{T_{}-T}{T_{}-T_0}$
