Square, rectangular, triangular, circular and semi-circular cross-section ofSAHduct have been used in literature. The triangular duct has minimumfriction factorvalues among others because it has less number of surface and its cross-section is near tocircular duct. SAH of triangular cross-section an...
Tags Cross Cross section Friction Friction factor Section Replies: 16 Forum: Mechanical Engineering S Open Channel Flow (mannings equation) rectangular section A rectangular concrete-lined channel is 2m wide with Manning's n 0.012 and a bed slope of 0.0025 m/m. Obtain the depth of flow whe...
Investigation of the dimensionless friction factor reveals that the overall channel pressure drop is governed by both the curvature effect as well as the area expansion effect. Due to the combined effect pressure drop for developing flow in a short, curved channel can be even less than that of ...
design a tension member w/ cross section... Homework Statement You are to design a tension member (square rod) with a cross section to carry a mass of 575 000 kg with a safety factor of 2 against yield and a safety factor of 3 against static fracture (overload). a) What is the de...

FE method for seismic analysis of inverted-siphon engineering Description of inverted-siphon structure An prestressed concrete inverted-siphon was designed for the Central Route of South-to-North Water Transfer Project, China, which consists of three boxes with transversal rectangular-section and is long...
aThe Nusselt number for a rectangular enclosure is given by Hollands et al. (1976). This number was multiplied by a factor of 2.6 which was used as a fitting parameter originating from the experiments described in Section 4, in order to accommodate the effects of the circular geometry of the...
Common parametric shapes include Tee, I, L, pipe, etc., in addition to the rectangular and circular shapes. The use of these parametric shapes in section design is quite common. Several design aids and computer programs have been developed that use these parametric shapes. For example, the ...
However, the values in the scale factor bands can be scaled up or down based on their SMR. Bands that have a lower SMR are multiplied by larger scaling factors because the quantization error for these bands has less impact, falling below the masking threshold. Consider this example. Say ...
Taking the rectangular launder as the example, this paper makes the derivation of the equations of each factor under the optimum hydraulic section of the watercourse, and taking the dichotomy as the example, introduces the calculating procedures of the optimum hydraulic factors under the optimum hydr...
