In the hydraulic network shown below, the height difference between the free surface of tank A and those of tanks B and C is 12 m. The pipes have a

constant diameter D and a constant Darcy friction factor f. The system is equipped with two valves. Numerical data are summarized in the Table below. 1) Neglecting minor losses in the system, find a relation between the velocity in section 2 (V2) and that(12 pts.)in section 3 (V3) when both valves are opened. b) Based on the result above, calculate the water flow rate into tank B. c) If minor losses were to be taken into consideration, which tank would encounter a more significant variation in its incoming flow rate, tank B or tank C? Justify your answer qualitatively.(5 pts.)
