Which of the following explains why it may be difficult to test a larger system? o Only new design components can be replicated, which makes reliable testing an issue.
O Laboratory results may not be collected due to the complicated nature of the system.
O It is not possible to test shape, environmental temperatures, and airflow all at the same time.
O Testing can only be completed when the entire larger system is replicated.

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.
