Water at a mass flow rate of 0.3 kg/s is cooled from 70oC to 30oC by passing it through a thin walled tube of diameter D=.05 m. Also air coolant passes over the outside of the tube in cross flow at T[infinity]=15oC with a velocity of 18 m/s. Assume negligible conduction in the wall and steady state conditions. Assume a film temperature for air of 300K

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.
