Asteel pipe (k=45.0 w/m-k) having a 5.0 cm o. d. is covered with a 4.2 cm thick layer of magnesia (k=0.07 w/m-k) which is in turn covered with a 2.4 cm layer of fiberglass insulation ((k= 0.048 w/m-k). the pipe wall outside temperature is 370k and the outside surface temperature of the fiber galss is 305k. what is the interfacial temperature between the magnesia and the fiberglass?

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.
