How many pounds of oxygen is transferred per day to a water volume (12334.8 m3) assuming one 9" air station and:
standard oxygen transfer efficiency (sote) = .10 %
standard cubic feet per minute (scfm) air flow = 1 scfm
approx density of air = 0.075 (lb/ft3)
the weight percent of oxygen in air = 0.232 %
minutes per day = 1440 min

10-14. (a) when 100.0 ml of weak acid ha were titrated with 0.093 81 m naoh, 27.63 ml were required to reach the equivalence point. find the molarity of ha. (b) what is the formal concentration of a- at the equivalence point? (c) the ph at the equivalence point was 10.99. find pk. for ha. (d) what was the ph when only 19.47 ml of naoh had been added?
