![]() It is therefore important to be aware of how viscosity can positively and negatively affect us. ![]() In short, viscosity plays a role in many aspects of our lives, from cooking to health care. Therefore, viscosity is an important factor in maintaining health. Conversely, if blood isn’t viscous enough, it can lead to bleeding disorders. If blood is too viscous, it can lead to clots which can be dangerous. Viscosity can also affect other fluids like blood. The viscosity of the water is therefore crucial in getting the pasta just right. On the other hand, if the water isn’t viscous enough, the pasta will become overcooked and fall apart. If the water is too viscous, the pasta won’t cook evenly and will stick together. This means that it takes 1 centipoise for water to flow 1 meter per second under the force of 1 pascal. Water has a viscosity of 1 cP at 20 degrees Celsius. Viscosity can also be expressed in centipoise (cP), which is the equivalent viscosity of a liquid with a dynamic viscosity of 1 Pa Viscosity is denoted by the Greek letter eta (η). Similarly, the air has lower viscosity and higher viscosity at low pressures. For example, water has lower viscosity and higher viscosity at lower temperatures. The viscosity of a given fluid can vary depending on its temperature and pressure. ![]() s), but the cgs unit of viscosity is the poise (P). ![]() The SI unit of viscosity is the pascal-second (Pa Viscosity is essential in many applications, including lubrication, flow control, and drag reduction. This behaviour is due to the increased motion of the molecules at higher temperatures. The viscosity of a fluid can be affected by temperature generally, viscosity decreases as temperature increases. ![]()
