(b) The results of laboratory filtration lests on a precipitate of CaCO3 suspended in water is presented in the table helow. A specially designed plate and frame press with a single frame was used. The frame had a filtering area of 0.0263 m2 and a thickness of 0.03m. All tests were conducted at 19C and with a slumry containing 0.0723 weight fraction CaCO3. The density of the dried eake was 1602kg/m3p=276kPa= constant - Determine (i) the filtrate volume equivalent in resistance to the filter medium and piping (ii) specific cake resistance (iii) the cake porosity and (iv) cake specific surface. 15
