常见介质粘度表全集文档.docx

1、常见介质粘度表全集文档常见物质的粘度表粘度，指物质的流动性 ( 或不流动性 )。任何流体都有粘度。液体粘度是它抵抗剪切力的一个尺度，在初始及持续流动时才体现出来。例如，粘度高的液体比粘度低的液体需要更大的动力来流动。流体粘度与温度有关。 粘度测量单位常用的有厘泊 cP，泊 P等，其换算过程：1厘泊(1cP)=1毫帕斯卡 .秒 (1mPa.s) 100厘泊(100cP)=1泊 (1P)1000毫帕斯卡.秒 (1000mPa.s)=1帕斯卡 .秒 (1Pa.s)水的粘度为 1 厘泊，流动十分容易。 可以根据流体的粘度，类比出我们常见的物质。1 厘泊 = 水；3厘泊 = 牛奶；34厘泊 = 植物油；

16、 between them. As the pressure increases, the volume decreases and the volume of these voids reduces, so normally increasing pressure increases the viscosity. Waters pressure-viscosity behavior 534 can be explained by the increased pressure (up to about 150 MPa) causing deformation, so reducing the

17、strength of the hydrogen-bonded network, which is also partially responsible for the viscosity. This reduction in cohesivity more than compensates for the reduced void volume. It is thus a direct consequence of the balance between hydrogen bonding effects and the van der Waals dispersion forces 558

18、in water; hydrogen bonding prevailing at lower temperatures and pressures. At higher pressures (and densities), the balance between hydrogen bonding effects and the van der Waals dispersion forces is tipped in favor of the dispersion forces and the remaining hydrogen bonds are stronger due to the cl

19、oser proximity of the contributing oxygen atoms 655. Viscosity, then, increases with pressure. The dashed line (opposite) indicates the viscosity minima.The variation of viscosity with pressure and temperature has been used as evidence that the viscosity is determined more by the extent of hydrogen bonding rather than hydrogen bonding strength.Self-diffusion is also affected by pressure where (at low temperatures) both the translational and rotational motion of water anomalously increase as the pressure increases.
