Figure 12.7 shows a branched system in which the pressure at A is 700 kPa and the pressure at B is 550 kPa. Each branch is 60 m long. Neglect losses at the junctions, but consider all elbows. If the system carries oil with a specific weight of 8.80 kN/m3, calculate the total volume flow rate. The oil has a kinematic viscosity of 4.8 x 10-6 m2/s.
