Parts X and Y are metal parts and produced separately, each requiring two press-working operations. Part X is routed through operations 1 and 2, and part Y is routed through operations 3 and 4. The two parts are then joined in a welding step (operation 5), and the assembly is routed to an electroplating operation (operation 6). The six operations have the following fraction defect rates: q1 = 5%, q2 = 15%, q3 = 10%, q4 = 20%, q5 = 13%, q6 = 8%. If the desired final quantity of assemblies is 100,000 units, how many starting units of parts X and Y will be required? There is no inspection or separation of defective units until after the final process, so defective units and good units are processed together through all production processes

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.
