Q.4. The slurry of CaCOa/water is to be filtered in a press having a total area of 8 m? and operated at a constant pressure drop of 2 atm. The frames are 36 mm thick. Assume that the filter medium resistance in the large press is the same as that in the laboratory filter. Calculate the filtration time required and the volume of filtrate obtained in one cycle. Given: viscosity of filtrate =6.6 X104 Ib/ft-s Density of the cake= 73 lb/ft3 Mass of solids deposited in filter per unit volume of filtrate = 10.9 Ib /ft3 Specific cake resistance = 12.7 X1010 ft/lb Filter medium resistance = 1.55 X1010 ft-1

An extraction experiment was carried out with the soxhlet extraction technique to obtain oil from a plant seed. In the experiment, 10 g of plant seeds were taken and extracted with 150 mL of hexane solvent, The oil-hexane mixture obtained at the end of the extraction will be separated in the rotary evaporator and the mass and percent extraction efficiency of the collected oil will be calculated. The data obtained at the end of the experiment are given in the table below. Accordingly, calculate the amount of oil obtained, the amount of oil obtained per 1 g of plant seed and the percent extraction efficiency by establishing a mass conservation balance around the rotary evaporator.

Aluminum atoms are to be diffused into a silicon wafer using both predeposition and drive-in heat treatments; the background concentration of Al in this silicon material is known to be 2.5 x 101⁹ atoms/m³. The drive-in diffusion treatment is to be carried out at 1050°C for a period of 4.0 h, which gives a junction depth x; of 3.0 μm. Compute the predeposition diffusion time at 950°C if the surface concentration is maintained at a constant level of 2 x 1025 atoms/m³. For the diffusion of Al in Si, values of Qd and Do are 3.41 eV and 1.38 x 10-4 m²/s, respectively. min
