Problem # 2: P-2 The Darcy friction factor fused calculating the pressure drop in pipes, is calculated by the following implicit formula: where x = 0.00005m is the material roughness, D = 0.5 m is the pipe diameter, Re= 6.0e is the flow Reynolds number. Find / using an appropriate scheme from chapter 3 (Newton or Secant). Use first estimate/estimates for the solution off close to 0.002.

A 600mm diameter horizontal pipe of length 2km branches into two pipes of 300mm and 450mm diameter, each 1.6km long (Fig. Q5). The 600mm pipe is at an elevation of 30m and connects reservoir A with water level 50m. The two branched pipes connects reservoir B with water level 100m. A pump is installed in the 600mm pipe and causes the flow from A to B. Calculate the required power of the pump to maintain a flow rate of Im®/s...
