Water at 20°C is to be pumped from one tank (ZA=5 m) to another tank at a higher elevation (ZB=13 m) through two 36 m long pipes connected in parallel, as shown in the figure. . The pipes are made of commercial steel, and the diameters of the two pipes are 4 and 8 cm.

Determine the total flow rate between the reservoirs and the flow rate through each of the parallel pipes. Hypothesis: 1.The flow is stationary and incompressible. 2. The input elects are negligible and therefore the flow is fully developed. 3. The elevation of deposits remains constant. 4. Minor losses and head loss in pipes other than parallel pipes are said to be negligible. 5. The flows through both pipes are turbulent (to be verified).
