2. (30 points) the shark tank at an aquarium houses 5 sharks that deplete the aquarium water of a total of 60.00 g of oxygen per hour. water from the tank is diverted through a bubbler unit that oxygenates the water using a stream of oxygen-rich air, and then is returned to the tank. at steady state, water enters the bubbler containing 0.000700 wt% o2 and exits the bubbler containing 0.001000 wt% o2. for every kilogram of the inlet water stream that enters the bubbler, 0.00500 mol of oxygen-rich air with an initial composition of 25.00 mole% o2 and 75.00 mole% n2 is fed through the bubbler. draw and label a flowchart for the process described. perform a degree of freedom analysis (dof) of the process. what are the flow rates of water entering the tank? what is the composition (in wt %) of the outlet air leaving the tank?

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.
