Water at 20o C flow a through the pipe system (19mm ID) shown at a rate of the 185 L/min (0.185m3/min).
If the loss coefficients for the 90o elbows and 45o elbow are 1.5 and 0.4, respectively. What is most nearly the sum of the minor (head) losses for the system? Useful relationships: v=V/A, hLminor=(v2/2g)(2k90+k45)
