An inexpensive food and beverage container is fabricated from 25-mni-thick polystyrene (k = 0.023 w/m k) and has interior dimensions of 0.8 m times 0.6 m times 0.6 m. under conditions for which an inner surface temperature of approximately 2 degree c is maintained by an ice-water mixture and an outer surface temperature of 20 degree c is maintained by the ambient, what is the heat flux through the container wall? assuming negligible heat gain through the 0.8 m times 0.6 m base of the cooler, what is the total heal load for the prescribed conditions?

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.
