water at 27c enters at a 40mm diameter tube with a mass flow rate of 2 kg/s the tube surface is maintained at a uniform temperature at 140 c. convection heat transfer to the water is 754000 w. what is the water temperature at the tube outlet

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.
