please help me with the answers also the steps to arrive at the answer

QUESTION2 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. Kt=1.1 for sharp edged entrance, KL=0.05 for the exit, K1=0.5 for bends (90)), and KL=10 for the wide-open globe valve. The diameter and roughness of the pipe are 80mm and c= 0.00015m, respectively. If the flow rate is 0.026m3/s, calculate the pressure drop between the two tanks.

A pipe with the diameter and length of 115cm and 2.7km. respectively, is connected at the bottom of the tank. Calculate the time after sudden opening of the valve for the velocity to reach 78% of its final velocity if h=150m and f= 0.030 Figure 1: Schematic illustration of a reservoir
