Water enters a wide, flat channel of height 2h with a uniform velocity of 2.5 m/s. At the channel outlet, the velocity distribution is given by the equation below, where y is measured from the centerline of the channel. Assume steady, incompressible flow, density 1000 kg/m3 . Determine the a. Mass flux at the entrance. (5 points) b. Mass flux at the exit. (5 points) c. Rate of change of mass with time within the channel. (5 points) d. Exit centerline velocity, umax. (5 points)

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.
