![]() Break oil is used in hydraulic brakes and is made out of high viscosity liquids. High viscous liquids are used to dampen the motion of various instruments.When blood is flowing via veins and arteries, the viscosity of the blood must be taken into account.In the Millikan oil drop experiment, to determine the charge of an electron, the concept of viscosity of the fluid is used.Thus, you need to use fluid with stable viscosity so that it does not react to heat or cold. Moreover, the fluid’s viscosity index is low then, during summer, it becomes thinner. Viscosity decides the oil consumption in your vehicle. While pouring oil into your vehicle, you need to take care of its viscosity.⇒ The importance of viscosity may be shown in the following areas: Why is viscosity important in everyday life? That is why it is easier to sail a boat in water than oil, as oil has high viscosity. As a result, high force is required to overcome the high friction existing between adjacent layers of fluid. The flow of viscous fluid slows down due to the hard shear. As high viscous fluids have high internal friction between adjacent layers of fluids, they can not shear easily. ⇒ High viscosity means the fluid feels high resistance between the adjacent layers of the fluid during their relative motion. What happens when the viscosity of fluid is too high? Fluid ViscosityĬps (centipoise) Air 0.002 Aceton 0.03 Water 1.00 Milk 2.00 Blood 10 Glycerine 1000 – 2000 Honey 2000 – 3000 Glue 3000 Ketchup 5000 – 20000 Peanut Butter 10 4 – 10 6 Pitch 2.3 x 10 11įluids with extremely high viscosity, such as peanut butter and pitch, act like solids. The viscosity of some common fluids is mentioned in the chart below, ranging from low to high. ![]() If a fluid has a viscosity greater than that of water, it is termed viscous if it has a viscosity less than that of water, it is considered mobile. That is why water can flow with ease than honey. But if you think of water and honey, then water has lower viscosity than honey. If you consider air and water, water has a higher viscosity than air as the air feels less resistance while flowing than water. #Viscosity of water free#Image credits: Pixabay Free image Examples: Honey, pitch etc. The movement of fluid with low viscosity is quick. The movement of fluid with high viscosity is sluggish or slow. To overcome friction or move through a fluid with low viscosity, one needs less force. To overcome friction or move through a viscous fluid with a high viscosity, one needs a lot of force. Fluids can easily shear due to their low resistance. Fluids cannot easily shear due to their high resistance. When a low internal friction force occurs during the relative motion of adjacent layers, the fluid is said to have a low viscosity. The following describes the difference between high and low viscosity: High viscosity Low viscosity When a high internal friction force occurs during the relative motion of adjacent layers, the fluid is said to have a high viscosity. The difference between high and low viscosity: Let’s talk about high viscosity vs low viscosity, which is the focus of this post. Viscosity can be grouped into two categories based on fluid flow resistance: ![]() Shear creates when liquid is poured in tube ![]()
