A can of pumpkin puree 8.73cm diameter by 11.43cm in height is being heated in a steam retort in which the steam pressure is 100 kPa above atmospheric pressure. The pumpkin has a thermal conductivity of 0.83Jm¹s-¹°C-1, a specific heat of 3770Jkg-¹°C-1 and a density of 1090kgm³³. The temperature in the can prior to retorting was 20°C. Plot out the temperature at the centre of the can as a function of time until this temperature reaches 115°C. Assume h is very high.
