The Air Duct Simulator that was used in Lab 4 was used again, but this time the 11-12 damper was not used. The components of the Air Duct Simulator include straight duct, bends, tees, dampers, filters, outlet grids and a variable speed fan. It has several measurement points, as shown by dots in the schematic below. Three dampers are located in these three branches. The duct diameters (in inches) are given in the schematic shown below. The three dampers are located between points 3-4, 11-12, and 17-18. A filter is located between 19-20. However, only the damper between points 3-4 was used in this lab. Figure 1 below depicts and dimensions the
