Your technician made measurements of metal concentrations in a metals recovery facility as shown in the flow sheet in Figure. Unfortunately, several of the data are missing. You know from past experience that 90% of the mass of metals entering a treatment system is recovered as a metals sludge containing a negligible amount of water. Assuming this percent recovery for the streams treated in systems B and X, calculate (a) the metal concentration in the water leaving the plant, cout, and (b) the rate that sludges (m1 + m2) are generated (g /hr) in the facility from the contaminated water streams. (Hint: the units of m and Qc are the same).
