Simulate the steady-state concentration distribution of a biodegradable chemical in the wastewater in an elongated tank. Use the backward differencing from finite difference method by dividing the pool into 10 equal sections (n = 10) and applying control-volume approaches. The system's characteristics are given as follows: Ac = 10 m Total Length = 100 m Velocity 100 m/hour Degradation rate, k = 2 hour- Dispersion coefficient, E = 2000 m/hour Inflow Concentration, Co = 1 mg/L = a) Create and write the system of equations that is used to calculate the concentration distribution and solve it using matrix methods. b) How much numerical dispersion occurs in the model solution?
