Water entering a pump at atmospheric pressure is delivered through a pipe network with two branches as shown in Fig. P12.4.1. The pressures at 3 and 4 are atmospheric. The diameters and lengths of sections 1-2, 2-3 and 2-4 are respectively (50 mm, 25 m), (32 mm, 30 m) and (25 mm, 25 m). The pressure head at the exit of the pump is 12 m. Calculate the water flow rates through the two branches 2-3 and 2-4.
