A stream has an average stream velocity of 0.92 [m/s] and an average depth of 1 [m]. Calculate the reaeration coefficient (Kr) at 20 C. b. Assume atmospheric pressure, 20° C temperature, and no stream contamination. Suppose the stream has an average chloride concentration of 5000 [mg/l]. What is the expected dissolved oxygen saturation concentration for the stream? c. With the same assumptions and conditions, the stream is receiving BOD contamination from an unknown source. If you have measured the dissolved oxygen (DO) in this stream and your DO probe reads 6.62 [mg/l]. How much is the DO deficit for this stream?
