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?

An array of m-50 thermoelectric modules is installed on the exhaust of a sports car. each module has an effective seebeck coefficient of sp of 0.143 5vk and an internal electrical resistance of r.-4 ? in addition, : (15 points each module is of width w 60mm and contains n=100 pairs of semiconducting pellets. each pellet hasan overall length of 2l-5mm and a cross-sectional area as 1.2 x 10'm and is characterized by a thermal conductivity of kpl2w rnk. the hot side of each module is exposed to exhaust gases at·p650c with hia4ow rrk while the osite side of each module is cooled by pressurized water at surface) and 156 °c (at the cool surface). 11s c with h: -500w/m'k. the modules are wired n series and the load resistance is r d=400ohm .the module surface temperatures, t, and ts are 183 "c (at the hot surface and 156c (at the cool surface) a)-draw a schematic of this scenario and label all parts. a. b. if the induced current, i, is 0.15 amps, what is the total power (pa) for one module? c. what is the total power harvest from the exhaust with all 50 modules?
