Problem #$3(50\%)$

Three reservoirs are connected at a common junction $J$ as shown below. Assume $C=120$ to calculate flow rate and correct flow direction in each pipe using following equation:

$h_f=(10\mathrm{.}67)(Q^{185})\frac{L}{C^{1\mathrm{.}85}}(D^{4\mathrm{.}87}),$ where $h_f(m),Q(\frac{m^3}{sec}),L(m),D(m)$

$($Hint: Solve $3$ reservoir problem graphically similar to Case I example$)$
