g . For a given flow rate through a smooth pipe, when comparing laminar and turbulent flow... (a) laminar flow will yield larger velocity gradients at the wall (b) turbulent flow will yield larger velocity gradients at the wall (c) laminar flow yields greater head losses (d) turbulent flow always provides lowest head losses (e) none of these answers

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.
