Give the meaning of the terms linear model, Slope, Undefined slope, linear interpolation.

Question

04 Q4 A waste effluent of 1.25 m/s with BOD, 183 mg/L, DO=0 mg/L and T = 20 °C is to be discharged into a river of 8 m³/s flow, BOD, = 2mg/L, DO -9.14 mg/L and T= 15 °C. At 20 °C, (K₁) is 0.3/day and (K2) is 0.9/day. The average velocity of the river is 0.8 m/s. 1) Is DO min within the environmental limitations? 2) At what distance is the maximum deficit located. 3) Draw the oxygen sag curve? Given the saturation concentration at 15 °C and at mixed temperature = 10.15 mg/L
