Less than HMD when flowing full.<\/p>\n<p>The hydraulic mean depth (HMD) is a dimensionless number that is used to characterize the flow of a fluid in a pipe or channel. It is defined as the ratio of the cross-sectional area of the flow to the wetted perimeter of the flow.<\/p>\n<p>The HMD for an egg-shaped sewer flowing two-thirds full is less than the HMD when flowing full because the wetted perimeter of the flow is greater when the sewer is flowing two-thirds full.
