1.The total density of a moist soil was determined to be 1760 kg/m3 when its water content was 10.0%. Assume the specific gravity is 2.7. Given this information, determine
(a) the phase diagram of the soil, (b) the void ratio, (c) the porosity, (d) the dry density, and (e) the saturated density.
2.Coal has about 2% sulfur. How many kilograms of sulfur would be emitted from coal fired plints in the US in 1 yr? US electricity production is about 0.28 * 10^12 watts, & coal has an energy content of about 30*10^6 J/kg
3.One gram of pepper is placed into a 100 mL beaker, and the beaker is filled with water to the 100 mL mark. What is the concentration of pepper in mg/L? What should one assume in this problem? What is the density of pepper? What is the volume of 1 g of pepper?
