give me the answer of this Consider a product to be sterilized if its coldest location during heating reaches 115C. Consider sterilization of potatoes where metal cans would be filled with water and potatoes (4 cm diameter) and the can is heated in steam at 121C. Assume symmetrical heating of potatoes and an overall heat transfer coefficient between the steam and the potatoes as 20 W/m2 K. The thermal diffusivity for potatoes is 1.5107m2 /s and the thermal conductivity is 0.4 W/mK. The potatoes are initially at 30C. Calculate the heating time needed for sterilization. You can use the Heisler chart
