Consider a solid cylindrical shaped bolt of diameter 25mm and length 5cm initially at temperature of 10C. Then the bolt is diopped in a faid at a temperature of 40C with a convective heat transfer coefficient of 35Wim2K. What would be the temperature of the boit 12 minutes ahter they are dropped in the fluid? The properties of the bolt are cp=460J/kgK,k=33.5 Whim K, and =7800kgm3
