In a sewage-treatment plant, a large concrete tank initially
contains 440 000 litres liquid and 10 000 kg fine suspended solids. To flush
this material out of the tank, water is pumped into the vessel at a rate of 40
000 litres h- 1. Liquid containing solids leaves at the same rate. Estimate
the concentration of suspended solids in the tank at the end of 5
h._______________________.
