Water flows in a branched pipe as shown in Figure QS below. The water flows from Pipe A with a 165 mm diameter dividing into two smaller pipelines, Pipe D with a 97 mm diameter and Pipe B with an 81 mm diameter. The velocity in the 82 mm pipe (B) is 0.5 m/s and in the 97 mm pipe (D) is 0.43 m/s. Figure Q8 Calculate the velocity in m/s and the mass flow rate in kg/s in the 165 mm pipe (A) if the density of the water is 1000 kg/m³. Enter your answers to three significant figures. Velocity: m/s. Mass Flow Rate: kg s-1.

C2. A conical tube is fixed vertically with its smaller end upwards and it forms a part of the pipeline. The velocity at the smaller end is 4.9 m/s and at the larger end is 2.5 m/s. The length of the conical tube is 1.3 m and the flow rate of the water is 127 liters/s. The pressure at the smaller end is equivalent to a head of 10.1 m of water. Considering the following two cases: (1) Neglecting friction, (without head loss) determine (i) the diameter at the smaller end in meter, (ii) the diameter at the larger end in meter, and (ii) the pressure at the larger end of the tube in m of water. (2) If a head loss (with head loss)in the tube,h = 0.0153(V1-V2)2, where V1 is the velocity at the smaller end and V2 is the velocity at the larger end, determine (iv) the head loss in m of water and (v) the pressure at the larger end of the tube in m of water. 6) the diameter at the smaller end in meter (ii) the diameter at the larger end in meter (iii) the pressure head at the larger end of the…
