MECHANICS OF LIQUIDS AND GASES

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 ... 更多

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 ... 更多

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 ... 更多

在表面张力实验中，讨论了液体的拉脱力/表面张力，以及浮力和表面自由能。   为了这个目的，当铝环均匀地在液体中移动时，以及当铝环被拉出液体时，作用在铝环上的力被确定。   环的位置和作用在环上的力都是同时测量的。这是通过PS400远程控制定位系统（1023414）和一个力传感器（1021676）实现的。数字数据在Coach7软件中被自动处理和可视化，因此，当环被拉出液体时，力的变化以图形方式显示。 ... 更多
