Three pipes of lengths 800m, 500m and 400m and of diameters 500mm, 400mm, and 300mm respectively are connected in series as shown in Figure 3. Water at 30°C is pumped through the pipes with the velocity in all pipe as tabulated in Table 1. The friction factor in all pipes are taken as 0.02. These pipes are to be replaced by a new single pipe of equivalent length 1700 m. All pipes are made of commercial steel B Figure 3: The water flow through three different pipe configurations Table 1: Pipe Configurations Pipe No Pipe Length (m) Pipe Diameter (mm) Velocity (m/s) A 800 500 2.000 B 500 400 3.125 C 400 300 5.556 the equivalent diameter of new single pipe, the flow regime for new single pipe, the friction factor for new single pipe and the head loss for new single pipe.
