Using Mechanical HVAC Section 1 and Section 2, place the vertical ducts coming down from the AHU, and connect them to the mechanical systems on the three levels. Use the default sizes from the AHU (12″x36″). What is the difference in length between the vertical supply duct, and the vertical return duct coming down from this AHU? [ft] ft. [in] in.
