Measurements of osmotic equilibrium of colloidal solutions, ranging from 170,000 to 20,000 in molecular weight, show that the negative buoyancy of the solute molecules is additive to the osmotic pressure. Seen together with earlier measurements of positive buoyancy of oil suspensions, these data confirm that the osmotic interaction between solute and solvent at equilibrium is purely a force-cou...

The current study deals with the reduced gravity and radiation effects on magnetohydrodynamic natural convection past a solid sphere. studied configuration is modeled using coupled nonlinear partial differential equations. obtained model transformed to dimensionless form suitable scaling variables. finite difference method adopted solve governing equation determine velocity temperature profiles...

SOLAS (Safety of Life at Sea), which was first enacted in 1914 as a result the Titanic disaster, presents mandatory requirements for ship safety, such adoption watertight bulkheads. However, accidents continue to occur despite development and application numerous safety technologies. In case marine accident, risk sinking or capsizing due flooding can be reduced by subdividing area, but shipbuil...

This study aims to investigate the effect of changes in buoyancy when a swimmer respires in a horizontal posture. We attempted to evaluate the levelness of swimmers' streamline posture by simultaneously measuring the lung capacity and buoyancy under water. The buoyancy was measured based on the changes in the vertical loads of the upper and lower limbs on the subjects' streamline posture under ...

When a fluid is injected into porous medium saturated with an ambient of greater density, the forms plume that rises upwards due to buoyancy. In near field injection point, adjusts its speed match buoyancy velocity medium, either thinning or thickening conserve mass. These adjustments are dominant controls on near-field shape, rather than mixing fluid, which occurs over larger vertical distance...

[1] This study describes a satellite‐based method to estimate simultaneously convective buoyancy (B) and entrainment rate (l). The measurement requirements are cloud‐top height (CTH), cloud‐top temperature (CTT), cloud profiling information (from radar and lidar), and ambient sounding. Initial results of the new method applied to A‐ Train data are presented. It is observed that tropical oceanic...
