SOLVED: 2-The following figure shows 3.2 m/s 2.6 m/s a typical duct layout. Design the duct system using the equal friction method. Take the D 19 m 18 m 23 m 9 m velocity of air in the main duct (A) as 10 m/s. Assume a dynamic loss coefficient of A E 0.57 for upstream to 9 m Fan downstream and 0.9 for upstream to branch and for 2.4 m/s the elbow. The dynamic loss coefficient for the outlets may be taken as 1.1. Find the total friction pressure losses in the section AD.
