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?

Amass of 3 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder device at 150 kpa. initially, 1 kg of the water is in the liquid phase and the rest is in the vapor phase. heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 500 kpa. heat transfer continues until the total volume increases by 20 percent. determine (a)-the initial and final temperatures, (b)-the mass of liquid water when the piston first starts moving, and (c)-the work done during this process. d)-show the process on a p-v diagram. you don't need to indicate p& v values, but clearly indicate where all states are located in the phase diagram.
