... the same reduction of driftable fines in all situations. In this paper, the effect of oil viscosity on the drift reduction ability of an oil emulsion is examined using a series of mineral oils of varying viscosities and the same emulsifier. In addition to the mineral oils, studies have also been carried...

... Adjuvants are known to enhance spray droplet retention on leaf surfaces and penetration of herbicide active ingredients through cuticles due to changes in physical properties such as density, viscosity, surface tension (SFT), and contact angle (CA) increasing leaf wettability. However, previous...

... The viscosity of fuels and lubricants determines whether a fluid is suitable for its intended use. For example, a fuel's viscosity affects how well it vaporizes or atomizes, which in turn affects combustion and energy output. A lubricant's viscosity affects how well it will maintain a film...

.... %Si dispersed nanofluids are observed at 0.1 vol. % of nanoparticle concentrations. Rheological studies of nanofluids show interesting findings as the viscosity of both types of nanofluids are observed to exhibit values lower than that of base fluid at lower concentrations and higher at higher...

Where applicable, alignment and overlap with existing ASTM methods and practices will be reviewed and future directions indicated. Recent improvements in the sensitivity...

... of materials, four were chosen for comparison to three commercially available benchmark dispersants in several typical pesticide suspension concentrates. The criteria used to compare the new to the old dispersants were: ability to reduce suspension viscosity, zeta potential, syneresis, and tendency...

... A new algorithm written in commercially available software controls programmable viscometers and rheometers so that multiple decades of apparent viscosity data may be acquired. This work is new and important because previous methods involved either: (1) very simple instrumentation providing...

... temperature and signal-noise on the pump outlet pressure and the case-drain flow provided better failure indicators than the case-drain flow. The fluids containing viscosity-index-improvers underwent large viscosity losses. No viscosity loss was observed for the fluids that did not contain the viscosity-index...

The results showed that surface tension of the liquid is an important factor in fabric wettability and penetration, but liquid viscosity which affects adhesion and rface density of liquid on the fabric also plays an important role. barrier fabrics capillary...

... Five samples of polymer modified asphalt were tested for viscosity at 60°C (140°F) using ASTM Test Method D2171 (Viscosity of Asphalts by Vacuum Capillary Viscometer). The samples were obtained from four different suppliers, and the polymers used included SB (styrene-butadiene), SBR (styrene...
