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?
