![]() ![]() For further definitions, go to Absolute (dynamic) and kinematic viscosity. One example of this is what is colloquially referred to as "the bends" (scientifically called decompression sickness). The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. One great use of Henry's Law is to calculate the various solubilities of gases in solutions under different pressures. Measured values span several orders of magnitude. ![]() Viscosity is measured using a viscometer. For instance, honey has a much higher viscosity than water. Water has a viscosity of 0.0091 poise at 25 ☌, or 1 centipoise at 20 ☌. It corresponds roughly to the intuitive notion of a fluid's 'thickness'. The dynamic viscosity of water is 8.90 × 10 4 Pa·s or 8.90 × 10 3 dyn·s/cm 2 or 0.890 cP at about 25 ☌. K H is Henry's Constant and is different for various substances and differs with temperature and comes in many different units. Dynamic viscosity is a material property which describes the resistance of a fluid to shearing flows. By comparing the kinematic viscosities of water and mercury under these. Where P is the partial pressure of either the volatile solute or of the solvent with a nonvolatile solute in it and C is the solubility of the volatile solute or the concentration of the solvent with a nonvolatile solute in it. While the water temperature is room temperature (300K) at the model inlet. The temperature dependence of the viscosity of water gives some testimony on this score. Mercury dynamic viscosity at temperature 300K is. An example of this would be oxygen or carbon dioxide in a soda. water molecule at 300 K).7 The next simplest candidate would. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. Henry's Law can also be used the describe the partial pressure of a volatile solute in a liquid as a function of its concentration in the liquid. As the concentration of the nonvolatile solute increases, the partial pressure of the solvent decreases. \): Henry's Law can illustrate the the relationship between the partial pressure of a solvent and the concentration of a nonvolatile solute dissolved in it. ![]()
