3. The Mohawk River in New York State flows from the west to east and passes several food processing facilities (Beechnut Baby Foods, Chobani Yogurt and LifeSavers Candy) in a stretch of river that is only 16 miles long. a. If the de-oxygenation constant kd is 0.195 day 1 and the temperature is a constant 20C find the dissolved oxygen concentration at point B, C, and LS. b. Then find the distance to the critical point downstream from the LifeSavers factory, the BOD remaining (Lt) and the DO at that critical point. B----------------12 miles C4 miles LS tc (See formula 5.24 on page 212 in the text for determining the re-aeration rate kr as a function of the depth of the stream and the velocity of flow)
