1000 kg/hr of a liquid solution of 60 wt% naphthalene (C10H8) and 40 wt% benzene (C6146) at 80 C is cooled to 10 C. The resulting solid and liquid phases are separated in a rotary drum filter. The process operates at steady state. Your job is to determine how well the drum filter is performing. You determine that the filtrate liquid flow rate is 505 kg/hr. (a) How much entrainment (kg entrained/kg solids) does the filter leave? (b) By how much does any entrainment change the recovery of naphthalene in the filter cake product or the purity of the products
