An air duct system is shown in Figure-1. The air enters at point A with a static pressure of 12 mm of water. The branch BE delivers 60m3/min at E, branch CF delivers 180 m3/min at F and the main duct delivers 240 m3/min at D. Using equal pressure drop method, find the duct dimensions. Assume free exit at each outlet. [CLO1, PLO1 15 Marks] 30 m 15 m C 15 m - 30 m 60 m 22.5 m F Figure 1 Duct System Develop a table for all three cases as below and fill with calculated values.
