SUMMARY
The hydraulic diameter is defined as \(D_h = \frac{4A_c}{p}\) and the hydraulic radius as \(R_h = \frac{A_c}{p}\), where \(A_c\) is the cross-sectional area and \(p\) is the wetted perimeter of a pipe. The misconception that the hydraulic radius should equal \(2\frac{A_c}{p}\) arises from a misunderstanding of the definitions. The relationship between diameter and radius does not apply in this context, as the hydraulic diameter and radius are distinct concepts used in fluid mechanics.
