A continuous horizontal flow setting basin is designed to treat a flow rate of $1\mathrm{.}1\frac{m^3}{s}(25mgd)$ and remove floc particles with an average settling velocity of $3\mathrm{.}6\frac{m}{h}.$ This settling velocity was measured in a laboratory in a quiescent condition at $15C.$ Determine the area of the basins and the basin area that needs to be covered with tube settlers. The tube settlers consists of a series of $50-$mm $(2-$in$.)$ square honeycomb cells tilted at a $60$ angle. The vertical height of the tube settlers is $0\mathrm{.}6m.$ Assume a countercurrent flow pattern is used.
