Objective:The objective of this experiment is to measure and plot the distribution of airflow in a 12in by 12in square duct section and to find the relationship between flowrate and damper position (angle).Introduction:Knowing how air flows through a duct allows engineers to better design HVAC systems and more efficiently circulate fresh air throughout a building. Dampers allow for the flowrate to be regulated. It gives the building managers the ability to control the amount of warm/cold air that is circulating to one part of a building without interfering with the flowrate of air to other parts ofa building. There are two type of damper that aregenerally used in air-handling units. The first kind is parallel blade, these types of dampers are good for 2 position configuration (either open or closed). The second type of dampers are the opposed blade, these types of dampers are good for regulating airflow. In this experiment we will be measuring the air velocity in a square (12in by 12in) duct. The velocity will be measured at nine separate point (see figure 1) using the TSI
