Figure 1 is a schematic of the plan of a rainwater harvesting system of a public facility located in a high-rainfall region of the New Orleans. Rainwater is collected over the 302 m2 roof and is collected into reservoirs A and D. Water. Overflow from these two reservoirs then flows into reservoirs B and Cas shown on the Figure. Reservoirs B and C spill off any excess water to the ground. All the four reservoirs are cylindrical with internal heights and diameters of 1.41 and 1.50 m respectively. The following data were collected as part of a study on the performance of the system. Daily water supply from the four reservoirs The daily levels of water in the four reservoirs The daily rainfall recorded by a rain gauge station located within 50 metres of the facility. The spreadsheet contains this data for the period 10 December 2019 to 10 January 2020. A. Using the provided data, determine the efficiency of rain water collection of the system using an optimization approach that seeks to minimize the differences between the measured daily water levels and the simulated water levels of the reservoirs. Apply daily time-step simulation of water levels based on the Behaviour B. Analysis method and assume that the proportions of the roof area draining into reservoir A and D are not necessarily equal (to 0.5) and could range from 0.1 to 0.9. Additionally, consider that the respective rainwater collection efficiencies for the roof areas draining to the two reservoirs could be unequal and range from 0.3 to 0.9. Solve the problem on Ms Excel spreadsheet applying the GRG nonlinear and the evolutionary optimizers of the Solver Add-in. Compare the results obtained from the two optimizers and inform which of the solutions (if any) seems more realistic. In addition, also inform what additional information you would obtain in order to verify the solutions obtained from the optimization.
