Water (at 20C) flows in the parallel pipes, as shown in the Figure Q3.1. The construction material of the pipes is plastic. Diameters of the first and second lines are 4 inch (26.9/2.65) and 14 inch (42.4/3.25) nominal, respectively. No elevation difference exits in the system. If the pressures at point A and at point B are 2.1 mWH and at 0.1lmWH, respectively, a. What is the volumetric flow rate in each branch of the parallel pipe? (Q1=?, Q2=?) [20 pts] b. What is the total volumetric flow rate at the main pipeline? (Qr=?) [5 pts] Note: Friction factor can be found from Blasius Equation PA P3 A L-10 m Figure Q3.1.
