A heated 6-mm-thick Pyroceram plate (rho = 2600 kg/m3, cp = 808 J/kg·K, k = 3.98 W/m·K, and α = 1.89 × 10–6 m2/s) is being cooled in a room with air temperature of 25°C and convection heat transfer coefficient of 13.3 W/m2·K. The heated Pyroceram plate had an initial temperature of 503°C, and is allowed to cool for 286 seconds. The mass of the Pyroceram plate is 7 kg. Determine the heat transfer from the Pyroceram plate during the cooling process. (Given: λ1 = 0.0998, A1 = 1.0017)

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
