Answer:
<em>Cout = 11mg/L</em>
Explanation:
Assume Steady State and CSTR, this means Qin = Qout
Given: Qin = 4 000m3/day
Cin = 25mg/L
V = 20 000m3
k = 0.25/day
Find: Cout = ?
outStarting from the mass balance equation for steady state 0 = QCin - QCout - kCoutV
manipulate the equation to get:
\(Cout=Cin(Q/Q+kV)\)
<em>Then simple plug in your givens:
</em>
<em>Cout = (25mg/L)((4000m3/day)/(4000m3/day + 0.25/day(20000m3))
</em>
<em>Cout = 11mg/L</em>
