3) A pump (h-40-7.906x10'xQ) delivers water (p-1000 kg/m, v-1.02x10 m/s) between 2 tanks, which are both open to atmosphere, located with a distance of H-20 m in the vertical direction and connected by 2 serial bolted union (civatal) pipes. The material, diameter and length of pipe-1 are galvanized steel, d-75 mm and L-130 m; there exist 1 (one) sudden inlet and 1 (one) 90 elbow. The material, diameter and length of pipe-2 are commercial steel, d-100 mm, L-50 m; there exist 1 (one) sudden exit and 1 (one) 45 elbow on pipe-2. Evaluate the volumetric flow rate (Q) of water in the system. (g=9.81 m/s)
