Nettet15. apr. 2015 · Select Intensity and Hydraulic Diameter next to the Turbulence Specification Method. Then enter 1% for Turbulence Intensity and 0.2m for Hydraulic Diameter. Click OK to set the boundary conditions for the inlet. The (absolute) pressure at the outlet is 1 atm. 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 Se mer 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: $${\displaystyle D_{\text{H}}={\frac {4V}{S}},}$$ Se mer • Equivalent spherical diameter • Hydraulic radius • Darcy friction factor Se mer jefferson avenue baptist church east point ga
