MECHANICS OF LIQUIDS AND GASES

In the surface tension experiment, the pull-off force / surface tension of liquids, as well as the buoyancy force and the surface free energy, are discussed. For this purpose, the force acting on an aluminum ring with a cutting edge ... more

The periodic variations of density caused by an ultrasonic standing wave pattern in a liquid act as an optical grating for the diffraction of a monochromatic parallel light beam that is transmitted in the direction perpendicular ... more

Objective: Determine the dynamic viscosity of an aqueous solution of glycerine Dynamic viscosity, the coefficient of proportionality between velocity gradient and sheer stress in a liquid, characterises how difficult it is for an object ... more

Objective: Measure the surface tension by the “breakaway” method To determine the surface tension of a liquid, a blade is immersed horizontally in the liquid and is slowly pulled out upwards while measuring the pulling force ... more
