Two parallel, aligned disks, 0.4 m in diameter and separated by 0.1 m, are located in a large room whose walls are maintained at 300 K. One of the disks is maintained at a uniform temperature of 500 K with an emissivity of 0.6., while the backside of the second disk (disc 2) is well insulated. Room is large enough to be considered as a black body. Assuming the discs are diffuse, gray surfaces, answer the following questions:
(a) Compute the view factors F12 and F13 [2 points]
(b) Draw the radiation network for this problem [2 points]
(c) Write an equation for radiation balance at surface 1 [2 points]
(d) Write an equation for radiation balance at surface 2 [2 points]
(e) Compute the temperature of the second disk. [2 points]

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.
