Note$)$ To generate a hydraulic head at $A,$ connect a reservoir $($water surface elevation $=100ft)$ to A with a

pipe in $10ft-$length and $2ft-$diameter. The $D-W$ friction factor $f$ is assumed as $0\mathrm{.}02$ for all pipes. Elevations

of all nodes are $0ft.$

$(1)$ Assuming a complete turbulence, compute $k_s$ for each pipe, and express them in the order of magnitude

of ${10}^{-3}$ feet for EPANET.

$(2)$ Present the pipe network diagram including final flow direction arrows resulted in EPANET $($copy &

paste the diagram from EPANET$).$

$(3)$ Present flow rate $($cfs$)$ and velocity $($fps$)$ for each pipe clearly $($copy & paste a table from EPANET$).$

$(4)$ Present pressure head $($ft$)$ and pressure $($psi$)$ for each junction clearly $($copy & paste a table from

EPANET$).$
