Because of the polarity of the bonds between the two hydrogen atoms and the oxygen atom, the molecule has slightly positive and slightly negative charges on both sides. Water is a universal solvent due to its polar hydrogen bonding, which allows it to dissolve a wide range of compounds. Specific gravity is a ratio and has no units. The specific gravity of water is 1 at 4 degrees Celsius.
It is sometimes expressed in terms of centistokes (cS or cSt) 1 stokes = 100 centistokes = 1 cm 2 s −1 = 0.0001 m 2 s −1.ġ000 grams, 35.274 ounces, or 0.264 US gallons The physical unit for kinematic viscosity is the stokes (St), named after George Stokes.
The kinematic viscosity of water at 20 ☌ is about 1 cSt. The difference between low viscous and high viscous fluids is given in table below: Low Viscosity Pascal seconds (Pa-s) are commonly used to quantify viscosity, a measurement of force equal to one kilogram per meter per second (kg/(ms)). For example, honey spreads much slower than water because honey has a higher viscosity than water. It explains the internal friction of a moving fluid. The viscosity of water can affect the performance of medical devices and treatments, and knowledge about the viscosity of water is important for the design of medical equipment and the development of treatments for various conditions.Ī fluid’s (liquid or gas’s) viscosity is its resistance to shape change or movement of adjoining sections relative to one another. The viscosity of water affects the texture and consistency of many foods and beverages, and knowledge about the viscosity of water is important for optimizing the texture of sauces and gravies, creating smooth and creamy desserts, and achieving the desired consistency in bread dough and other baked goods. Understanding the behavior of fluids is important in a variety of fields, and knowledge about the viscosity of water is used to model and predict the behavior of fluids in natural systems and to design structures. Knowledge about the viscosity of water is essential for optimizing fluid-handling equipment and manufacturing processes.
