Extracted text: A mass balance for pollutant in a well-mixed lake can be given as follows: de V = M – Fc – kVc dt Given volume v =1x10ʻ m, volumetric flow rate F =1x10° m/hr, mass flow rate M =1x10 g/hr and k = 0.2 m05/g.5/hr. a) Estimate the steady state concentration using the modified secant method. Employ an initial guess of c = 3 g/m and & = 0.5. The acceptable approximate percentage error must be less than 0.5%. Perform the calculation up to 4 decimal points. b) The steady state concentration also can be estimated with fixed-point method as follows: M- Fc C = M – kvve C = or as kV F Between these two equations, identify which one will converge for initial guess of c = 3 g/m. Perform three iterations only and determine the approximate percentage error.
