mostly need help w part B

3) In 1970 total phosphorus loadings to the Great Lakes were Units W tonnes/year 3000 Huron 3500 Superior Using the parameters Parameter Units Mean depth M Surface area 106 m2 Volume Outflow Superior 146 82,100 12,000 67 Huron 59 59,750 3,500 161 109 m3 109 m3/year and assuming that total phosphorus settles at a rate of approximately 16 m/year, a) Calculate the steady-state concentration for each lake, assuming a feedback of 30x109 m3/yr of flow from Huron to Superior. Assume inflow from other sources into Huron has no concentration. Using the concentrations from part a as initial conditions, determine the response of each lake if their loadings are terminated at time t-0. b) 3) In 1970 total phosphorus loadings to the Great Lakes were Units W tonnes/year 3000 Huron 3500 Superior Using the parameters Parameter Units Mean depth M Surface area 106 m2 Volume Outflow Superior 146 82,100 12,000 67 Huron 59 59,750 3,500 161 109 m3 109 m3/year and assuming that total phosphorus settles at a rate of approximately 16 m/year, a) Calculate the steady-state concentration for each lake, assuming a feedback of 30x109 m3/yr of flow from Huron to Superior.
