Material is a sphere with 3 cm diameter and a heat capacity of 4.0 kJ/kg*K, a density of 800 kg/m3 a thermal conductivity of 0.7 W/m*K. The heat transfer coefficient of the surrounding air is 14 W/m2*K. If the initial temperature inside the furnace prior to the start of sterilization is 15 °C, final temperature the 160°C (320°F). How long should the procedure last to obtain sterile material for disposal? Note: If you think you need more information than you are provided with here to solve this problem, you can use assumption. And please explan each steps.
