The Hydraulic Institute has just completed the task of developing a new ANSI/HI standard on Rotodynamic (Centrifugal) Slurry Pumps covering nomenclature, definitions, applications, and operation. The standard provides examples of all the different types of pumps available and has an extensive section on definitions. Slurries and their effect on performance and wear are covered. A slurry service...

The energy sector in Brazil produces liquid biofuels as bioethanol and biodiesel. most common technique to produce biodiesel is the transesterification of oils extracted from biomass. Rice processing generates grain bran, an agricultural residue. one main countries that this grain. Therefore, objective study was a renewable biofuel using vegetable oil bran via homogeneous basic transesterificat...

BACKGROUND The pendulum test of Wartenberg is a technique commonly used to measure passive knee motion with the aim to assess spasticity. We used this test to evaluate changes of the knee angular displacement, passive stiffness and viscosity in rheumatoid arthritis patients. Stiffness and viscosity represent passive resistances to joint motion associated with the structural properties of the jo...

This work is devoted to investigating stochastic turbulence for the fluid flow in one-dimensional viscous Burgers equation perturbed by Lévy space-time white noise with periodic boundary condition. We rigorously discuss regularity of solutions and their statistical quantities this dynamical system. The include moment estimate, structure function energy spectrum turbulent velocity field. Further...

introduction we aimed to introduce a 6-universal-prismatic-spherical (ups) parallel mechanism for the human jaw motion and theoretically evaluate its kinematic problem. we proposed a strategy to provide a fast and accurate solution to the kinematic problem. the proposed strategy could accelerate the process of solution-finding for the direct kinematic problem by reducing the number of required ...

New measured data for density, (ρ), dynamic and kinematic viscosities, (μD μc), refractive index, (nD), are presented at T = 298.15 K p 0.1 MPa binary ternary mixtures containing dibutyl ether, 2-butanol, cyclohexane. As a result, the derived properties estimated based on data. Excess molar volume, (VE), viscosity deviation (ΔμD), in (ΔnD), as properties, fitted using Redlich–Kister equation. I...

Fundamental physical constants play a profound role in physics. For example, they govern nuclear reactions, formation of stars, synthesis and stability biologically vital elements. These are high-energy processes discussed particle physics, astronomy cosmology. More recently, it was realised that fundamental extend their governing reach to low-energy properties operating condensed matter system...

In order to produce high-viscosity and high-toughness asphalt for ultra-thin overlays, the conventional cement was modified with high-content SBS micro carbon fiber (MCF). The performances of were studied by tests penetration, softening point, ductility, kinematic viscosity, multiple stress creep recovery (MSCR), dynamic shear rheometer (DSR) bending beam (BBR). Mixture properties rutting, low-...

Abstract. Observations of sediments at subduction margins appear to divide them into two classes: accretionary and erosive. Accretionary are dominated by accretion thick piles (>1 km) from the subducting plate, while tectonic erosion is favored in regions with little or no sedimentary cover (<1 km). The consequences styles for dynamics remain poorly resolved. In this study, we used 2-D nu...
