(i, j are the indices representing the velocity components); P represents the pressure (N m−2); μe = (μ + μt) stands for the effective viscosity (N s m−2), where μ and μt refer to the dynamic and turbulent viscosities, respectively; ρ is the density (kg m...
Given: fc'=25MPa(normal-density concrete) fy=400MPa There are 3 steps to solve this one. Solution
Alt- hough the root system size depends on tree age and root density, the root distribution model is established at a certain point in the early stage of root growth and is not changed after this stage. Thus, the influences of different ages of black locust and Chinese pine on the ...
Note: many of the values depend on manufacturing process and purity/composition.Material Yield strength (MPa) Ultimate strength (MPa) Density (g/cm³) ASTM A36 steel 250 400 7.8 Steel, API 5L X65 (Fikret Mert Veral) 448 531 7.8 Steel, high strength alloy ASTM A514 690 760 7.8 Steel...
Two very effective insulations were identified: A proprietary insulating concrete and corrugated metal plates. The former has very low density, is quite strong, and has a low thermal conductivity. The latter is inexpensive, easily placed into position and leads to quite low boiling rates. Also ...
Without clouds over the study area, the image quality is good and the data product Level 1 T, having been geometrically corrected on the basis of terrain, can be used directly. The concrete data sources are shown in Table 6 and the technical flow chart can be found in Supplementary Fig...
of regional multi-functional areas. Thirdly, this paper provides a supporting framework for optimizing land structure and pattern reconfiguration. The researchers have conducted an in-depth empirical study in an important ecological region of the Yellow River basin, thus providing a concrete and ...
The main objectives of the future wireless communications systems are to provide a high-capacity and high-data rate to offer ultra-reliable and low-latency communications [1,2,3,4], but also communications in scenarios with high user density, such as indoor hotspots [5]. The initial deployment...
Service centers of government agencies in wireless city projects have the following characteristics: Open areas with obstacles including bearing columns, working desks, and few concrete walls Not high user density Certain per-user bandwidth r...
