Question: 3 . Air flows in a horizontal 1 0 0 - ft - long, ( 2 4 times 2 4 ) -

3. Air flows in a horizontal 100- ft -long, \(24\times 24\)-inch square duct at the rate of 5000 cfm . The air then flows through a size transition fitting into 200-ft of \(36\times 36\)-inch square duct. The size transition has an equivalent length of 12 feet. Calculate the velocity (fpm) in each segment, and the head pressure loss across the entire duct system, in inches of water column. (3 points)
