Determine the flow rate in the system shown in Figure. Consider f=0.02, a single loss k=0.2, and a pipe diameter of 0.2 m. Estanque A Elevación=15m 80m 40m Estanque B K=0.2 Elevación=0

Water at 10° C (v = 1.307 x 10^-6 m^2/s) flows from a tank A to B, through a cast iron pipe (ɛ = 0.26 mm) 20 m long and with a flow rate of Q = 0.0020 m3/s as shown in the figure. The system has 6 90° elbows (KL = 1.5) and the singular loss coefficient at the inlet KLentration = 0.5 and at the outlet KLoutlet = 1. Determine the necessary diameter for the system pipe.
