In other words, a 12 inch round duct or pipe has a hydraulic diameter of 12 inches. Interestingly enough, a 12 inch square duct (one square foot) also has a hydraulic diameter of 12 inches. But, if you hold the cross-sectional area constant at one square foot and vary the aspect ratio , the hydraulic diameter starts to decrease as the aspect ratio the duct increases above 1.
