Unformatted text preview: There is negligible input/output other than these two streams. Flow in and out is 10 3 m 3 /day. The inflow stream contains a contaminant with concentration equal to 3.4 mg/L. i) Determine the steadystate concentration of the contaminant in the pond if the contaminant decays in the pond at a rate equal to 0.001 mg/Lday. (15 pts) ii) Determine the steadystate concentration of the contaminant in the pond if the contaminant decays in the pond at a first order rate given by: R = k . C, where k = 0.01/day and C has units of mg/L. (15 pts) 4. Stella Assignment 1—posted on Blackboard in the Assignments folder. A document called ‘Stella Introduction’ is also posted on Blackboard....
