Prob. $8\mathrm{.}5\mathrm{.}53$ p$.$ IP$-114[$Ans: $0\mathrm{.}018\frac{m^3}{s}$;$0\mathrm{.}013\frac{m^3}{s}.$ Assume a pipe roughness of $=0\mathrm{.}00009m.$

$8\mathrm{.}5\mathrm{.}53$ WP SS With the valve closed, water flows from tank $A$ to $tankB$ as shown in Fig. P$8\mathrm{.}5\mathrm{.}53.$ What is the flowrate into $tankB$ when the valve is opened to allow water to flow into $tankC$ also? Neglect all minor losses and assume that the friction factor is $0\mathrm{.}02$ for all pipes.
