3.10. Filtration time. In a filtration process, 100 g are obtained

of a cake that forms a bed of 80 cm3

with a porosity of 0.2. Time

filtrate was 20 min and the volume of filtrate collected in this period

of 2 L. The resistance of the filter medium is considered negligible and the cake

incompressible.

Required: Estimate the time to form a 300 g cake
