Problem $36$

Three pipes are joined such that Pipe $3$ flows into Pipe $2$ into Pipe $1.$ The flowrate in the pipes are $5f\frac{t}{s}.$ Pipe $3$ has diameter of $12in.$ Pipe $2$ has diameter $12in.$ Pipe $1$ has diameter $16in.$ Losses at each manhole in the system is $1ft$ Losses along Pipe $3$ are $2\mathrm{.}5ft.$ Losses along Pipe $2$ are $1\mathrm{.}5ft.$ Losses along Pipe $1$ are $3\mathrm{.}5ft.$ The Total head at the downstream end of Pipe $1$ is $150ft.$ Plot the EGL and HGL for these sewer lines.
