Intensity and hydraulic diameter翻译
The hydraulic diameter, DH, is a commonly used term when handling flow in non-circular tubes and channels. Using this term, one can calculate many things in the same way as for a round tube. When the cross-section is uniform along the tube or channel length, it is defined as See more In the more general case, channels with non-uniform non-circular cross-sectional area, such as the Tesla valve, the hydraulic diameter is defined as: $${\displaystyle D_{\text{H}}={\frac {4V}{S}},}$$ See more • Equivalent spherical diameter • Hydraulic radius • Darcy friction factor See more WebThe characteristic length-scale for a channel of width w and depth h is the hydraulic radius, Rh = wh/P, where P is the wetted perimeter. For an open channel P = (2h + w) and for a …
