For the horizontal series-parallel system of the figure below, all pipes are 7 cm diameter asphalted cast iron (e-0.12 mm) filled with water at 20°C (-998 kg/m'.-0.001 kg/m.s). The total flow rate is Q-0.0269 m/s, the lengths of segments A and Care LA-250 m and Le - 150 m, and velocity in segment A is l'A-2.04 m/s. Neglect all minor losses.

Question 1
For the horizontal series-parallel system of the figure below, all pipes are 7 cm diameter
asphalted cast iron (r= 0.12 mm) filled with water at 20°C (- 998 kg/m', -0.001 kg/m.s).
The total flow rate is Q-0.0269 m/s, the lengths of segments A and Care LA-250 m and Le
- 150 m, and velocity in segment A is l'A- 2.04 m/s. Neglect all minor losses.
