A gravity-driven flow system is used to feed oil from tank (A) into a second tank (B). The elevation difference between the tanks is 55m. The system also includes 110m of galvanized iron piping with 2 bends (90) and a wide-open globe valve. The density and dynamic viscosity are =820kg/m3 and =0.0239kg/ms, respectively. KL=1.1 for sharp edged entrance, KL=0.05 for the exit, KL=0.5 for bends (90), and KL=10 for the wide-open globe valve. The diameter and roughness of the pipe are 80mm and = 0.00015m, respectively. If the flow rate is 0.026m3/s, calculate the pressure drop between the two tanks
