The following data have been collected on the flow rate (i.e., volume of water treated per time) and the solids concentration (i.e., mass of solids per volume of water) over an 8-hour period. As an environmental engineer, you have been asked to estimate the average sludge production rate for this facility. Time Period (hr) 0-1 1-2 2-3 3-4 4-5 5-6 6-7 7-8 Average flow rate (ft³/min) 10 12 15 17 22 26 42 14 Suspended solids concentration (mg/L) 90 112 133 166 154 189 211 144 Complete the following and show your work: a) Use a spreadsheet tool (e.g., Microsoft Excel or Google Sheets) to estimate the mass of solids removed during each hourly period. Assume 100% removal of particles in the treatment plant. b) Determine the total mass of solids removed over the entire 8-hour period, in kg. c) Assuming the sludge produced is 2% solids (where 0.02 [mass solids]/[mass of solids + water]), estimate the sludge mass produced over the entire 8-hour period. d) Assuming the density of the sludge is 1.02 kg/L, estimate the volume of sludge produced over the entire 8-hour period.
