Solids analysis is one of the important parameters for assessing water quality. Use the following data for calculating total solids (TS), volatile solids (VS), dissolved solids (DS), total suspended solids (TSS), and total volatile suspended solids (TVSS) all in mg/l. A sample volume of 150 ml was used in performing all solids analysis: Tare mass of evaporating dish = 24.3520 g Mass of evaporating dish plus residue after evaporation @ 105 °C = 24.3970g Mass of evaporating dish plus residue after ignition @ 550 °C = 24.3850g Mass of Whatman filter and tare = 1.5103g Mass of Whatman filter and tare after drying @ 105 °C = 1.5439g Residue on Whatman filter and tare after ignition @ 550 °C = 1.5199g

A Standard Proctor Test was completed according to Method A described in Chapter 12. The following laboratory data was obtained: Mass of mold = Mass of moist specimen and mold = Volume of compaction mold = Mass of container= 51.5g Mass of container plus moist soil= 261.85g Mass of container plus oven-dried soil= 231.83g Determine the Moisture content, w. (expressed as a percentage, 1 decimal place) Your Answer: 1.98 kg 3.718 kg 0.0009438m3

The total mass of a sample is 102.40 g, the total volume is 48.00 cm3, the water content is 20.00%, and the relative density (relative density of the solids) is 3.20. Find the total density (ρ), dry densoty (ρD), and the void ratio (e). Enter your answers in the spaces provided below. keep your answers to two decimal places.
