常见介质粘度表

水的黏度表(0～40℃)水的物理性质F3??? Viscosity decreases with pressure(at temperatures below 33°C)Viscous flow occurs by molecules moving through the voids that exist between them. As the pressure increases, the volume decreases and the volume of these voids reduces, so normally increasing pressure increases the viscosity.Water's pressure-viscosity behavior [534] can be explained by the increased pressure (up to about 150 MPa) causing deformation, so reducing the 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] 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 closer 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.。

常见介质的近似粘度
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力来流动。一些液体显示出不同的粘度特性。牛顿型流体（N）在给定的温度下有稳定的粘度而与流速无关；水和大多数油是牛顿型流体。

常见介质的近似粘度参考表
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) 蠕动泵的传输是靠弹性软管的弹性来完成工作的，因此被传送的流体粘度的大小会在很大程度上影响蠕动泵的流量，一般情况下，蠕动泵所标明的流量是以水为参照物的流量值。

若传输的液体有粘度，选型时候应留出适当的余量，以免达不到所需要的流量值。

水的粘度为1 厘泊，流动十分容易。

可以根据流体的粘度，类比出常见的物质。
