(d) Ca(HCO3)2 = 150 mg/L; Mg(HCO3)2 = 200 mg/L; CaSO4 = 180 mg/L; MgCl2 = 95 mg/L; CaCl2 = 137 mg/L; turbidity = 15 mg/L; NaCl = 58.5 mg/L. Calculate: (i) Carbonate and non-carbonate hardness in degree Clark. (ii) The cost of limesoda process, if lime (95% pure) is Rs.200/10 Kg and soda (86%pure) is Rs. 400/10 Kg for softening of 150,000 liters of hard water using Al2(SO4)3 as a coagulant @ 28.5 mg/L. (iii) A hard water sample having 530 ppm CaCO3 equivalent hardness was completely softened on passing over a zeolite bed. The exhausted bed was subsequently regenerated using 75 liters of 45 percent brine solution. Calculate the quantity of hard water that has been softened using zeolite softener.

A mass of soil coated with a thin layer of paraffin wax weighs 700 gm and soil alone weighs 650 gm. When soil sample is immersed in water it displaces 400 mL of water. The specific gravity of soil is 2.65 and that of wax is 0.9 and water content is 20%, ., = 1000 kg/m3. Void ratio of soil is W
A container of volume 3 × 10-³ m³ weighs 10 N. Dry sand was poured to fill the container. The container and the sand together weighs 53 N. The porosity of the soil will be (Take G₂ = 2.7, Y = 9.81 kNm/³)
An irregular lump of saturated clay with a mass of 605.2 g was coated with paraffin wax. The total mass of the coated lump (in air) was 614.2 g. The volume of the coated lump was found to be 311 ml by displacement in water. After carefully removing the paraffin wax, the lump of clay was over-dried to a dry mass of 479.2 g. The specific gravity of the hardened wax is 0.90. Determine the water content, specific gravity, dry unit weight and void ratio.
