Water is being pumped from reservoir A to an end nozzle C, where it will be discharged at atmospheric pressure as shown in Figure 2. A pump is used to reach the required velocity at the end nozzle. As shown in Figure 2, the length of suction pipe, Pipe 1, is 200 m with a dimeter of 200 mm. The delivery pipe, Pipe 2, is 850 m long with a diameter of 300 mm. The internal roughness of the pipe is k, = 0.03 mm. The local head losses at pipe entrance (from reservoir A) and pipe exit (at end nozzle C) can be calculated based on minor loss coefficients of 0.50 and 0.10, respectively. The kinematic viscosity is u = 1 x 10-6 m²/s and the water density is p = 1000 kg/m³.

Question

Water is being pumped from reservoir A to an end nozzle C, where it will be discharged at atmospheric pressure as shown in Figure 2. A pump is used to reach the required velocity at the end nozzle. As shown in Figure 2, the length of suction pipe, Pipe 1, is 200 m with a dimeter of 200 mm. The delivery pipe, Pipe 2, is
