Water is supplied through a horizontal pipeline compose

Water is supplied through a horizontal pipeline composed of series-connected pipes of different lengths and diameters (Fig. 1).
The water flow through the pipeline is 50 l / s. The temperature of the water supplied through the pipeline is 20 ° C.
Required: 1. On graph paper to build the characteristics of the pipelines of individual sections and the total characteristics of the pipeline.
2. Determine the total pressure loss in each pipe.
3. Determine the flow regime in each pipeline.
4. Determine the coefficients of hydraulic friction of each pipeline.
Given: l1 = 500 5N2 = 5000m; l2 = 300 5N2 = 4800m; l3 = 150 5N2 = 4650m; d1 = 300 mm = 0.3m; d2 = 250 mm = 0.25m; d3 = 150mm = 0.15m; Δ1 = Δ2 = Δ3 = 0.2mm = 0.0002m; Q = 50l / s = 0.05m3 / s
