Problem $3$

GIVEN: A sanitary sewer line is to be designed to serve a new housing development. When first installed, the initial peak flow is estimated as $\backslash (0\mathrm{.}1\backslash$mathrm$\{$ft$\}^\{3\}/\backslash$mathrm$\{$sec$\}\backslash ),$ but at full buildout the sewer line is expected to accommodate a peak flow of $\backslash (0\mathrm{.}7\backslash$mathrm$\{$ft$\}^\{3\}/\backslash$mathrm$\{$sec$\}\backslash ).$

REQUIRED: Answer the following questions.

a$)$ Determine the minimum diameter for a commercially$-$available pipe.

b$)$ Determine the minimum slope for a commercially$-$available pipe.

c$)$ If the existing infrastructure limits the slope of the sewer line to $\backslash (0\mathrm{.}2\backslash \%\backslash ),$ what would you recommend as the design engineer?

SOLUTION:
