Sanitary Sewer Systems $-$ Homework Problems

Refer to WV$64$CSR$47$ for all problems. Assume all manholes are $4-$ft in diameter.

What is the design flow required to serve a new subdivision with a maximum population of $1000$ in Bluefield, WV$?$

What size of pipe and minimum slope must be selected in order to carry the design flow calculated in problem $1?$

In WV$,$ what are the required minimum slopes for an $8-$inch, $12-$inch, and $24-$inch pipe?

The invert elevation of exiting Manhole $A(MH-A)$ is $937\mathrm{.}27$ ft $.$ A $10-$inch sewer pipe at a slope $0\mathrm{.}28\%$ connects to the entrance of MH$-$B $353-$ft away. A $15-$in$.$ pipe joins the MH$-$B perpendicular to the $10-$in$.$ line; a $21-$in$.$ line is exiting MH$-$B$.$ What is the invert elevation of a$.)$ the exiting $21-$in$.$ line b$.)$ the invert of the $15-in.$ line where it joins $MH-B?$
