If the volume of an object increases while the density of the fluid remains the same, the buoyant force will ___. A. decrease B. remain the same C. increase D. become zero 相关知识点: 试题来源: 解析 C。解析:如果物体的体积增加而流体的密度保持不变,根据浮力公式,浮力会增加。
The device for measuring the density or viscosity of a fluid flowing in a closed passage (2) includes a rotor (5) whose speed of rotation is directly dependent on the rate of flow of the fluid. The rotor (5) is connected to an activatable and deactivatable brake means (13, 14, 15)...
A MEMS Device for Measuring the Physical Properties of Fluids We present a novel Micro-Electromechanical System (MEMS) sensor that upon immersion quickly measures a fluid's density and viscosity. The operational principal involves the influence of the fluid on the resonance frequency and quality of....
N Okong'O,J Bellan - 《Journal of Fluid Mechanics》 被引量: 133发表: 2002年 Model for dynamics of structural glasses We also examined the effective thermodynamics of systems quenched below this divergent temperature and subsequently heated. The result is a peak in the ... IS Graham,L Piché...
We study, theoretically and experimentally, the suspension’s internal energy, equilibrium pressure-density relations, and their stability for both adiabatic and isothermal processes. We show that the elastic multistability of the capsules endows the fluid with multistable thermodynamic properties, including...
In particular, the mobility of extraelectrons can be used as a probe to study the electron states in a disordered medium and the relationship among the electron-atom interactions and the properties of the fluid.DOI: 10.1007/978-1-4615-2540-0_17 ...
Characterization of MCM-41 Using Molecular Simulation: Heterogeneity Effects We present new experimental data and molecular simulation results for the adsorption of nitrogen in MCM-41. We show that models in which the solid-fluid in... MW Maddox,JP Olivier,KE Gubbins - 《Langmuir》 被引量: ...
The device for measuring the density or the viscosity of a fluid flowing in a closed passage (2) comprises a rotor (5) whose speed of rotation is directly dependent on the flow velocity of the fluid. The rotor (5) is connected to a device activatable and deactivatable brake (13, 14, ...
