[translate] aSince the viscosity of air is much less than that of water, this term is safely ignored. 因为空气黏度比那是较少水,这个期限安全地被忽略。[translate]
The term “diastole” denotes relaxation, and the term “systole” refers to contraction [3]. 6.1 Diastole During the diastolic phase, blood flows into the right atrium from the superior and inferior vena cava, which elevates the internal pressure of the right atrium. When the right atrial ...
; 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−3) and S is radon source term (Bq m−3 s−1)....
(9), i.e. there is no other way to write a term which only contains\sin (\omega t)and other term which contains\sin (\omega t)and is multiplied by\cos (\omega t). A last manipulation can be made to transform the bracket expressions into a power sum of\sinfunctions, by using ...
First, we need to change the definition of the volume force to , as such: The term rho0 refers to the reference density . Next, we evaluate the reference density and the reference viscosity from the material properties in a table of variables: ...
The biodegradability property can apply to both bio-based and petrochemical-based materials. As a result, the term bioplastics is used to refer to: biodegradable and non-biodegradable bio-based plastics, and petrochemical-based biodegradable plastics. In relation to the bio-based origin, threshold ...
[33]. This was because the screen area’s efficacy increased as the impurity level decreased. The study pointed out that finer screens may be more suitable for filtering rubber particle contaminants. Temperature can also decrease the polymer’s viscosity, thus lowering the pressure build-up behind...
kB = 1.38 × 10−23 J K–1 is the Boltzmann constant, T = 298.15 K room temperature, and η is the solution viscosity. The solution viscosity was assumed to depend linearly on the protein concentration according to: $$\eta ={\eta }_{0}\left({\eta }_{{{...
37 The term “configuration” refers to a state in which the drop is at rest in a position of metastable equilibrium. Associated with each configuration are the characteristic interfacial areas ΩSLj, ΩLj and a characteristic Helmholtz energy, A j ....
