Kerosene at $25C$ is flowing in the system shown in Fig. $1.$ The total length of $49\mathrm{.}8mm$ ID galvanized

iron tubing is $30m.$ The two $90$ bends are standard elbows and tank B is open at the top. Calculate

the volume flow rate $(\frac{m^3}{s})$ into tank $B$ if a pressure of $150$kPa is maintained above the kerosene in

tank A$.$
