Two plates are held together by square stainless steel bars with thickness of 12 mm. each bar has a thermal conductivity of 12 w/mk, a specific heat of 500 J/kgK, and a density of 7.9 g/cm^3. The bars are situated in between the two plates, and they are occasionally submerged in hot liquid at 300°C with a convec- tion heat transfer coefficient of 96 W/m2.K. The length of each bar that is exposed to the hot liquid is 25 mm with an initial temperature of 20°C. The maximum use temperature allowed for ASTM A479 904L bars is 260°C . If the bars are sub- merged in the hot liquid for 5 min, will they be in compliance with the ASME code? How long will it take for the bars to reach the maximum use temperature?
