P$6\mathrm{.}127$ In the five$-$pipe horizontal network of Fig. P$6\mathrm{.}127,$ assume that all pipes have a friction factor $f=0\mathrm{.}025.$ For the given inlet and exit flow rate of $2f\frac{t^3}{s}$ of water at

$20C,$ determine the flow rate and direction in all pipes. If $p_A=120lb\frac{f}{i}{n}^2$ gage, determine the pressures at points $B,C,$ and $D.$
