The inlet flow was turbulent and fully developed, and the results were compared with data for water in the same geometry and with previous published Newtonian and non-Newtonian data in a smaller expansion of diameter ratio equal to 1.538. An increase in expansion ratio led to an increase in ...
The expander played an important role as the output power equipment of the ORC, and single screw expander (SSE) had a great prospect due to its unique structure and working characteristics. Besides expander efficiency, expansion ratio was another important performance parameter, which has a great ...
from 1992 to 2000 with a mean annual growth ratio of 5.826%. The total urban area is close to the results from Landsat TM data with overall accuracy over 98%. However, the Kappa coefficient is low. The same threshold value results in over-extraction of urban extent in large-area urban ...
decline, we overlaid global maps of blue (that is, surface and ground) and green (that is, rainfall) water stress22to evaluate the fraction of AEI changes that have occurred in water-stressed regions (that is, unsustainable) since the start of the century. This new understanding of the su...
Definitions, online calculator and figures and tables with water properties like density, specific weight and thermal expansion coefficient of liquid water at temperatures ranging 0 to 360°C (32 to 680°F).

Sulfate reacts with the hydrated tricalcium aluminate in the ...
The pore water pressure can be subsequently deduced from the radial equilibrium equation. Extensive parametric studies have been made of the effects of K-0 consolidation anisotropy (including also the subsequent stress-induced anisotropy) and past consolidation history (overconsolidation ratio) on the ...
23, we derived changes in the variability of SSH and ocean temperature by comparing the first 95 years (1906–2000, historical period) to the later 95 years (2006–2100, future period); thus, there was a large ratio between the climate change signal and any higher-frequency variability ...
The Hydration Characteristics and Expansion Machanism of Expansive Cement at Low W/B Ratio The hydration characteristics and expansion impetus of three kinds of cement paste under freeand confined-curing conditions were investigated, which were r... LU Lin-Nu,HE Yong-Jia,LI Yue,... - 《武汉理...
An experimental study of water flow in rectangular xurographic microchannels incorporating 90° miter bends with different channel widths in each leg is reported. A set of 12 microchannels, with channel depth approximately 105 micrometers and aspect ratio ranging from 0.071 to 0.435, were fabricated...
