head loss coefficientorifice platerecirculationOrifice plates as an effective energy dissipator have been used in hydropower projects. The head loss coefficient, relating directly to the energy dissipation ratio, is an important index of these elements. This coefficient and parameters such as the ...
2) energy loss coefficient 能量损失系数 3) local head loss coefficient 局部水头损失系数 1. Numerical simulation oflocal head loss coefficientfor water-keeping weir; 保水堰局部水头损失系数的数值模拟 2. Under the certain supposition condition,suddenly expands or reduces thelocal head loss coefficientaccor...
Communication energy consumption coefficient model for cluster heads communicating with sink node is set up, on the basis, sink node builds the multi-hops path tree for cluster heads in opposite direction, and determines the data forwarding energy consumption coefficient value of every cluster head. ...
As listed inTable 2, similar to the variation of the steady driving force,SEAalso varies in a large range depending on the semi-conical angle and radius of the die as well as thefriction coefficient. Thealuminum alloytubes dissipate a larger amount of the energy per unit mass than steel on...
where V is the monthly cumulative rainwater volume in m3, AR is the rooftop area in m2, I is the rainfall intensity in mm/month, and Cr is the runoff coefficient, ranging from 0.75 to 0.95 for roofs. When rainwater is considered as the water resource in the MPS, rainfall characteristics...
k is the regression coefficient [37]. 7. Results and Discussion In our current investigation, we aimed to replace part of heavy gasoline with light methanol and to observe the carbon-redundant effects on fuel characteristics. Due to such exchange, fuel properties, such as calorific value, ...
Transfer functions were generated from accelerometers attached to the leg and head of ten male runners. A rigid body model was used to estimate the net energy absorbed at the hip, knee, and ankle joints. There was an increasing degree of shock attenuation as stride length increased. The ...
However, the magnitude of the EPOV6 coefficient of the middle-aged subgroup is relatively small. The seemingly unrelated estimation test is used to test for age differences in the coefficients between models using Wald chi-squared tests (Weesie, 2000). We find a significant difference between ...
First, generate cluster head by random competition in the nodes which have advantage in energy; next determine the internal structure of clusters by calculating dynamically tightness coefficient of each cluster, after that, optimize transmission path between cluster heads through improved multi-objective ...
Influence of interfacial energy on the coefficient of friction for phosphatidylcholine bilayer surface phosphate (–PO4H/–PO4−) groups. Over the pH range 6–9, the phosphate group is charged (–PO4−), while the amino group (–NH2) is neutral. The pH 7.4 is a working value when ...
