Design thickness of the wall to maintain steady heat flux ??
Consider a machine surface that is made of a 5-mm thick alu- minum with a thermal conducdvity of 237 W/m-K. During operation the machine dissipates about 300 W/m2 of heat to the surroundings, and the inner aluminum surface is at 150OC. To prevent machine operators from thermal burns, the machine surface can be covered with insulation. The aluminum/ insuladon interface has a thermal contact conductance of 3003 W/m2-K. What is the thickness required for the insuladon layer with a thermal conductivity of 0.06 W/m K in order to maintain the surface temperature at 45°C or lower?

Homework problem for unsteady-state heat transfer Consider a product to be sterilized if its coldest location during heating reaches 115°C. Consider sterilization of potatoes where potatoes (4 cm diameter) is heated in steam at 121°C. Assume symmetrical heating of potatoes and the heat transfer coefficient between the steam and the potatoes is 20 W/m² K. The thermal diffusivity for potatoes is 1.5 × 107m²/s and the thermal conductivity is 0.4 W/m K. The potatoes are initially at 30°C. 1) Calculate the heating time needed for sterilization. 2) Calculate the temperature at the center of the potato after heating 1000 s and 2000 s. Plot how the temperature at the center changes with time t. 3) Calculate the temperature at the surface of the potato at 2000 s. Qualitatively plot how the temperature changes across the apple at t = 2000 s.
