An experimental filter press, with an area of 0.0414 m2, was used to filter the BaCO3 aqueous suspension at a constant pressure of 267 kPa. The filtration equation obtained was: [1]

V [m^3] , t [s]

a) Using the same suspension and equal conditions in a leaf filter with an area of 6.97 m2, how long will it take to obtain 1.00 m3 of filtrate? b) After filtration, the cake is washed with 0.100 m3 of water. Calculate the washing time

Vt=10.25106V+3.4103
