Description

Given the incoming average flow, the number of settling tanks and the geometric characteristics of each one, checks whether it fits the Brazilian standards for domestic sewage treatment plants.

\begin{align*} 20 \leq Q/A \text{ (m³/m² . day) } \leq 24 \end{align*}

\begin{align*} 3.0 \leq Y_L \text{ (m) } \leq 3.5 \end{align*}
