What is the aspect ratio of a duct measuring 32 x 22?

• A. 1.0 : 1
• B. 1.25 : 1
• C. 1.5 : 1
• D. 2.0 : 1

Answer: (C)

To determine the aspect ratio of a duct, you divide the larger dimension by the smaller dimension. In this case, the dimensions of the duct are 32 inches and 22 inches. First, identify the larger dimension, which is 32 inches, and the smaller dimension, which is 22 inches. Now, perform the division: 32 ÷ 22 = 1.4545... When expressing this as a ratio, it is commonly rounded to two decimal places. This results in an aspect ratio that can be approximated as 1.5:1. This aspect ratio indicates how the width of the duct compares proportionally to its height, which can be important for understanding airflow dynamics and sizing in HVAC applications. A higher aspect ratio generally means a narrower and taller duct, which can influence factors such as air resistance and flow efficiency.
